Abstract:
There are a variety of opinions regarding the influence of retained austenite and carbides on the properties exhibited by carbonitrided steels. In this paper, the development of a model marking relationship between phase composition, and properties of hardened carbonitrided steel has been presented. A summary of the impact of structure on properties is provided in Table 1. In the study reported here, the impact of thermal processing conditions on retained austenite and carbides was examined for carbonitrided and hardened 20 (C22), 20H (20Cr4), 15HN (17CrNi6-6) and 16HG (16MnCr5) steels. The models that are reported were experimentally validated. In particular, the results obtained for structure with respect to hardness and abrasive wear resistance were discussed for carbonitrided and hardened 20H (20Cr4) steel.

Abstract:
The change in phase composition and fine texture occurring in the ferritic-pearlitic 0.18C – 1Cr – 3Ni – 1Mo – Fe, 0.3C – 1Cr – 1Mn – 1Si – Fe and 0.34C – 1Cr – 1Ni – 1Mo – Fe steels under electrolytic plasma carbonitriding was investigated by transmission electron microscopy (TEM) method conducted on thin foils. Carbonitriding was implemented by surface saturation with nitrogen and carbon in aqueous solution under the temperature of 800 – 860 °C during 5 minutes. All steels were investigated before and after carbonitriding. It was ascertained that in the original state steel is given as a mixture of grains of pearlite and ferrite. Carbonitriding has led to creation of modified layers: the bigger was the amount of pearlite before the beginning of carbonitriding, the thicker was modified layer. Carbonitriding resulted in significant qualitative changes in phase state and structure of steel. It was revealed that in the surface area of modified layer along the matrix, there were also particles of other phases: carbides, nitrides and carbonitrides. In the course of removing from the surface of carbonitrided sample, their complete set and volume fractions decrease and at the end of modified layer only one carbide phase is present in all steels, i.e. cementite. It was found that matrix of all steels after carbonitriding is tempered packet (lath) and lamellar martensite. In the surface area of carbonitrided layer the volume fractions of lath and lamellar martensite depend on the original state of steel – the bigger was the amount of pearlite in steel the less lath martensite and the more lamellar martensite was formed. Such a dependency cannot be observed in the central area, and at the end of carbonitrided layer volume fractions of martensite packets and plates are commensurate.

Abstract:
Depth-Profiles of Corrosion Properties of Carbonitrided AISI 405 SteelElectrochemical polarisation characteristics of AISI 405 type stainless steel, carbonitrided in fluid flow, are presented. The evaluation of the corrosion resistance of carbonitrided stainless steel was carried out by using the so called progressive thinning method, consisting in determination of polarisation characteristics on increasingly-deeper situated regions of the top layer. This method made it possible to determine changes in particular corrosion parameters read out from potentiokinetic polarisation curves, thus enabling the depth profiles of these parameters. The resistance of the AISI 405 steel against acid corrosion was determined in acidified 0.5M sulphate solutions having three different pH values, namely 1, 2 and 4. The thickness of the carbonitrided layer has been evaluated on the basis of the spectrophotometric analysis of carbon content and microhardness on the cross section of the surfacial layer.

Abstract:
To study the influence of indentation on the fatigue strength of untreated and carbonitrided specimens of S38C steel, the fatigue limit of specimens with and without indentations was tested. Fracture surfaces were observed using scanning electron microscopy (SEM). The results show that the fatigue strength of the untreated specimen decreases with increasing dimension of indentation, without significant difference compared to the predicted results. Compared to the fatigue limit of the untreated specimen, those of the carbonitrided specimen and the carbonitrided specimen whose compound layer was polished were improved by 12% and 40%, respectively. The fatigue strength of the carbonitrided specimen decreased sharply with increasing indentation size because of the presence of microcracks in the compound layer. When the compound layer was removed, the fatigue limit was observed to be less sensitive to indentation than that of the carbonitrided specimen.

Abstract:
The purpose of this paper is to study the effect of chemical heat treatments on cavitation erosion resistance of the 304 stainless steel. Three types of diffusion layers are prepared on the 304 stainless steel using gas nitriding, gas carburizing, and carbonitriding treatments. Phase composition and surface microstructure of the diffusion layers are characterized by X-ray diffraction and scanning electron microscopy. And then, the cavitation erosion behavior of the diffusion layers are tested and compared with the one of the 304 stainless steel. The cavitation test is performed in an ultrasonic vibration system integrated with an electrochemical workstation. The mass loss, scanning electron microscopic morphology, and electrochemical test are adopted to assess the surface damage of the diffusion layers. A measurement for the mechanical properties of the diffusion layers shows that the hardness and the elastic modulus of the gas nitrided diffusion layer, carbonitrided diffusion layer, carburized diffusion layer, and 304 stainless steel are 5.3 GPa and 260 GPa, 4.2 GPa and 236 GPa, 4.0 GPa and 210 GPa, 2.5 GPa and 193 GPa, respectively. A cavitation erosion test of 14 h shows that mass loss of the gas nitrided diffusion layer, carbonitrided diffusion layer, carburized diffusion layer, and 304 stainless steel is 5.19 mg, 8.97 mg, 14.37 mg, and 6.62 mg, respectively. The electrochemical test results also indicate that the gas nitrided diffusion layer has a higher corrosion resistance than the carburized diffusion layer, carbonitrided diffusion layer, and stainless steel under cavitation erosion condition. As a conclusion, the gas nitrided diffusion layer is capable of enhancing the cavitation erosion resistance of the stainless steel, while the carburized diffusion layer and carbonitrided diffusion layer increases the mass loss of the stainless steel under cavitation erosion condition.

Abstract:
A carbontirided layer was produced on 20CrMnTi steel by plasma electrolytic carbonitriding (PEC/N). Scanning electron microscopy with an energy dispersive X-ray analysis was employed to study the morphology and chemical composition of the carbonitrided layer. Hardness of the layer was measured using a microhardness tester, and the phase structure was determined by X-ray diffraction. The results show that a compact carbonitrided layer can be obtained on the surface of 20CrMnTi steel. The thickness of the layer increases with carbontriding time. When the sample was treated at 120V for 20min, the thickness is 45μm and the highest microhardness is 766HV0.05. The carbontrided layers are composed of Fe3C, Fe5C2, ε-Fe3N and α-Fe.

Abstract:
To upgrade the operational stability of the tool at LLC “Karbaz”, Sumy, Ukraine, carbonation of tools and samples for research in melts of salts of cyanates and carbonates of alkali metals at 570–580 °C was carried out to obtain a layer thickness of 0.15–0.25 mm and a hardness of 1000–1150 НV. Tests of the tool in real operating conditions were carried out at the press station at LLC “VO Oscar”, Dnipro, Ukraine. The purpose of the test is to evaluate the feasibility of carbonitriding of thermo-strengthened matrix rings and needle-mandrels to improve their stability, hardness, heat resistance, and endurance. If the stability of matrix rings after conventional heat setting varies around 4–6 presses, the rings additionally subjected to chemical-thermal treatment (carbonitration) demonstrated the stability of 7–9 presses due to higher hardness, heat resistance, the formation of a special structure on the surface due to carbonitration in salt melts cyanates and carbonates. Nitrogen and carbon present in the carbonitrided layer slowed down the processes of transformation of solid solutions and coagulation of carbonitride phases. The high hardness of the carbonitrified layer is maintained up to temperatures above 650 °C. If the stability of the needle-mandrels after conventional heat treatment varies between 50–80 presses, the needles, additionally subjected to chemical-thermal treatment (carbonitration) showed the stability of 100–130 presses due to higher hardness, wear resistance, heat resistance, the formation of a special surface structure due to carbonitration in melts of salts of cyanates and carbonates. Keywords: needle-mandrel, matrix ring, pressing, heat treatment, carbonitration.

Abstract:
Les traitements thermochimiques de carbonitruration sont utilisés dans l’industrie automobile pour conférer à des pièces (pignons…) des résistances à la fatigue et à l’usure élevées. Ils consistent à générer des gradients de carbone et d’azote en surface des pièces par diffusion dans le domaine austénitique à haute température et à les refroidir rapidement pour obtenir les gradients de microstructures, de propriétés mécaniques et de contraintes résiduelles de compression en surface désirés pour les propriétés en service. Cette thèse a pour objectif de mieux comprendre les effets de gradients de teneur en carbone et d’azote sur la genèse des contraintes internes au cours du refroidissement en relation avec les cinétiques de transformations de phases ainsi que les distributions de contraintes résiduelles en fin de traitement par une démarche expérimentale et de modélisation. Du point de vue expérimental, la première étape est l’élaboration d’échantillons de laboratoire à gradients de teneur en carbone et d’azote contrôlés représentatifs des pièces. Puis, les cinétiques de transformations de phases et les évolutions des contraintes internes ont été analysées par diffraction des rayons X haute énergie (synchrotron) au travers des gradients de composition chimique en mettant en œuvre une nouvelle méthodologie. A notre connaissance, c’est la première fois que les contraintes internes ont été mesurées in situ dans des échantillons à gradients. Des résultats nouveaux et inattendus ont été obtenus en présence d’azote : il a été montré que la chronologie des transformations de phases entre le cœur et la surface enrichie en azote de l’échantillon est complètement inversée par comparaison avec le cas plus classique de la cémentation (enrichissement en carbone seul) ce qui conduit à un profil inversé de contraintes résiduelles avec des contraintes de traction en surface et des contraintes de compression à cœur. Ce comportement a été relié à l’accélération des transformations de phases diffusives dans la couche nitrurée qui diminue sa trempabilité. Un modèle couplé thermique-transformation de phase-mécanique a aussi été développé pour prévoir les évolutions de températures, les cinétiques de transformations de phases, les évolutions de contraintes internes ainsi que les distributions de microstructures finales, duretés, contraintes résiduelles dans des échantillons à gradients. Le modèle de calcul des transformations de phases développé dans une thèse antérieure a été implémenté dans le code de calcul par éléments finis Zebulon. La loi de comportement du matériau est thermo-élasto-viscoplastique et tient compte des déformations de transformations de phases (changement de volume et plasticité de transformation). Tous les paramètres matériau (thermomécaniques et thermo-physiques) sont fonction de la température, des phases en présence et de la teneur en carbone et en azote. Ils ont été déterminés par des caractérisations expérimentales d’éprouvettes enrichies de manière homogène en carbone et en azote et en se basant sur des données « maison ». Les simulations numériques ont confirmé et permis de comprendre de manière détaillée les évolutions complexes des microstructures et des contraintes internes liées aux gradients combinés de carbone et d’azote. Les comparaisons calcul-expérience montrent que la simulation permet de prévoir les principales tendances révélées par les observations expérimentales. Les écarts sur les niveaux de contraintes sont principalement attribués à la sous-estimation par le calcul des taux d’austénite résiduelle due au fait que le modèle métallurgique actuel ne tient pas compte de la stabilisation de l’austénite au cours du refroidissement
Carbonitriding thermochemical treatments are used in automotive industry for improving fatigue and wear resistance of mechanical parts. These treatments aim to generate gradients of carbon and nitrogen in the surface aera of the piece by diffusion in the austenitic field, and with the following quenching the desired gradients of microstructures, mechanical properties, and compressive residual stresses on the surface are obtained. The objective of the PhD thesis is to better understand the effects of carbon and nitrogen gradients on the development of internal stresses during cooling in relationship with the phase transformations as well as on the residual stresses distributions after cooling. The approach consists first of the elaboration of laboratory samples with controlled carbon and nitrogen gradients representative of the parts. Then, the kinetics of phase transformations and the internal stresses evolutions have been analysed experimentally by in situ High Energy (synchrotron) X-ray Diffraction throughout the chemical composition gradients thanks to a specific new methodology. To our knowledge, it is the first time internal stresses can be measured in situ during cooling in gradient specimens. Unexpected results have been obtained in nitrogen enriched samples; it has been shown that the chronology of phase transformations between core and surface is inversed as compared to the more classical case of carburizing leading to completely inversed residual stress profiles with tensile stresses in the nitrogen enriched layer and compression in the core. It has been related to the acceleration of transformation kinetics in the nitrided layer that decreases its hardenability. A coupled thermal-metallurgical-mechanical model has been developed too to predict temperature evolutions, phase transformations kinetics, internal stresses evolutions as well as final microstructure, hardness and residual stress distributions in the gradient samples. The metallurgical model developed in a previous study has been implemented in the finite element code Zebulon. The thermomechanical behaviour law of the material is thermoelastoviscoplastic including transformation strains (volumic variations and transformation plasticity strains). All material parameters (thermomechanical and thermophysical parameters) are considered as temperature, phase and carbon and nitrogen dependent; they have been determined from experimental characterizations on carbon and nitrogen homogeneously enriched specimen and in house data. The simulations allowed to confirm and understand more in details the complex microstructure and internal stresses evolutions due to combined nitrogen and carbon gradients. The comparison between calculated and experimental results shows that the simulation gives the main tendencies of the experimental observations. The main discrepancies on the level of residual stresses are attributed to the underestimation of the retained austenite fractions as the present model does not take into account its stabilization during cooling

A Study on the Composite Carbide，Nitride and Carbonitride Coating of Die Steels in a Fluidized Bed Abstract The implementation of a fluidized bed CVD process for the formation of hard wear-resistant , corrosion-resistant , oxidation-resistant , dense and strong adhesion coatings of carbides , nitrides and carbonitrides of die steels is feasible since it can lead to a flexible surface modification technology combining adaptability with reducing capital and operational costs . In this paper , FBCVD is coupled with conventional CVD and TRD(Thermo-Reactive Diffusion & Depostion Process) for the production of coatings . The method developed has the advantages of being simple , clean and environmentally friendly compared with conventional coatings . Die Steels(SKD11 & SKD61) were used for the substrates . For different coating species , this research involved a treating agent consisting of a powder mixture of Al2O3 with titanium powder , chromium powder or V-Fe powder . HCl was used as activator of the process . During the coating process , the bed can be fluidized by inert gas or gas mixtures like Ar , Ar+H2 , Ar+N2 etc . The present study reports on the characteristics of formation of TiC/TiN composite coating , CrC/VC composite carbide , CrCN , CrN on die steels . The experimental parameters such as temperature , time , gas composition ratio , powder content ratio , HCl concentration and prenitrided condition were investigated to appraise their effects on the growth rate of the coating species . The optimal processing condition was obtained from the evaluation of the experimental parameters . The growth rate and the microstructure of the coatings were investigated by measuring the weight change , the thickness and the hardness . EPMA was carried out to analyze the chemical composition of the coatings . XRD was also performed to examine the structure and compounds of the coatings . Coating investigations of corrosion resistance , oxidation resistance , adhesion strength and wear test reveal the coating effects in a fluidized bed . According to the results , TiC/TiN composite coating behaved better in adhesion strength and wear protection compared with TiC and TiN coating . Deposition of TiC/TiN composite coating can effectively retard the oxidation at temperature below 650℃ . The mechanical properties of CrC/VC composite carbide coating just lie between CrC and VC . The hardness and the tribological potential of CrC/VC composite carbide coating have been enhanced through the presentation of vanadium carbide . Coatings of CrCN or CrN were observed to have excellent adhesion strength and pronounced corrosion resistance to nitric acid(69%) and sulfuric acid(96%) . Both of CrCN and CrN were shown to have the highest oxidation resistance and proved to be oxidation resistant to at least 700℃ . Among the Ti-based coatings and the Cr-based coatings , CrCN had particularly high wear-resistance potential and CrN had the lowest oxidation rate .

Abstract:
The effect of Laves phase (Fe2Nb) formation on the Charpy impact toughness of the ferritic stainless steel type AISI 441 was investigated. The steel exhibits good toughness after solution treatment at 850°C, but above and below this treatment temperature the impact toughness decreases sharply. With heat treatment below 850°C the presence of the Laves phase on grain boundaries and dislocations plays a significant role in embrittlement of the steel whereas above that temperature, an increase in the grain size from grain growth plays a major role in the impact embrittlement of this alloy. The toughness results agree with the phase equilibrium calculations made using Thermo–Calc® whereby it was observed that a decrease in the Laves phase volume fraction with increasing temperature corresponds to an increase in the impact toughness of the steel. Annealing above 900°C where no Laves phase exists, grain growth is found which similarly has a very negative influence on the steel’s impact properties. Where both a large grain size as well as Laves phase is present, it appears that the grain size may be the dominant embrittlement mechanism. Both the Laves phase and grain growth, therefore, have a significant influence on the impact properties of the steel, while the Laves phase’s precipitation behaviour has also been investigated with reference to the plant’s manufacturing process, particularly the cooling rate after a solution treatment. The microstructural analysis of the grain size shows that there is a steady increase in grain size up to about 950°C, but between 950°C and 1000°C there is a sudden and rapid 60 % increase in the grain size. The TEM analysis of the sample that was annealed at 900°C shows that the Laves phase had already completely dissolved and cannot, therefore, be responsible for “unpinning of grain boundaries” at temperatures of 900°C and higher where this “sudden” increase in grain size was found. The most plausible explanation appears to be one of Nb solute drag that loses its effectiveness within this temperature range, but this probably requires some further study to fully prove this effect. During isothermal annealing within the temperature range of 600 to 850°C, the time – temperature – precipitation (TTP) diagram for the Laves phase as determined from the transformation kinetic curves, shows two classical C noses on the transformation curves. The first one occurring at the higher temperatures of about 750 to 825°C and the second one at much lower temperatures, estimated to possibly be in the range of about 650 to 675°C. The transmission electron microscopy (TEM) analyses show that there are two independent nucleation mechanisms that are occurring within these two temperature ranges. At lower temperatures of about 600°C, the pertaining nucleation mechanism is on dislocations and as the temperature is increased to above 750°C, grain boundary nucleation becomes more dominant. Also, the morphology of the particles and the mis-orientation with the matrix changes with temperature. At lower temperatures the particles are more needle-like in shape, but as the temperature is increased the shape becomes more spheroidal. The effect of the steel’s composition on the Laves phase transformation kinetics shows that by lowering the Nb content in these type 441 stainless steels, had no significance effect on the kinetics on precipitation of the Laves phase. However, a Mo addition and a larger grain size of the steel, retard the formation of the Laves phase, although the optimum values of both parameters still need further quantification. The calculation made for the transformation kinetics of the Laves phase, using the number density of nucleation sites No and the interfacial energy, as the fitting parameters in this work, demonstrated a reasonable agreement with experimental results.

Abstract:
Abstract Carbonitriding is a modified form of gas carburizing. It is performed in a closed furnace chamber with an atmosphere enriched with a gaseous compound of carbon and nitrogen. This chapter provides information on the carbonitriding of steels, the applications of carbonitriding, the typical case depths, and the hardenability of carbonitrided parts. In addition, the chapter also discusses the processes involved in quenching, tempering, and distortion of carbonitrided steels.

Abstract:
Abstract Gaseous ferritic nitrocarburizing, like salt bath nitrocarburizing, involves the introduction of carbon and nitrogen into steel in order to produce a thin layer of iron carbonitride and nitrides, the "white layer" or compound layer, with an underlying diffusion zone containing dissolved nitrogen and iron (or alloy) nitrides. This chapter first presents the development and principles of the process. It then discusses the properties of gaseous ferritic nitrocarburized components. The chapter also presents the applications for the ferritic nitrocarburizing process. It provides an overview of the safety considerations.

Abstract:
Abstract Low pressure carbonitriding and pressurized gas quenching heat treatments were conducted on four steel alloys. Bending fatigue tests were performed, and the highest endurance limit was attained by 20MnCr5+B, followed by 20MnCr5, SAE 8620+Nb, and SAE 8620. The differences in fatigue endurance limit occurred despite similar case depths and surface hardness between alloys. Low magnitude tensile residual stresses were measured near the surface in all conditions. Additionally, nonmartensitic transformation products (NMTPs) were observed to various extents near the surface. However, there were no differences in retained austenite profiles, and retained austenite was mostly stable against deformation-induced transformation to martensite during fatigue testing, contrasting some studies on carburized steels. The results suggest that the observed difference in fatigue lives is due to differences in chemical composition and prior austenite grain size. Alloys containing B and Nb had refined prior austenite grain sizes compared to their counterparts in each alloy class.

Abstract:
The aim of this study was to characterize the microstructure of microalloyed linepipe steels. The steels investigated were X70 (0.04 wt% C - 0.02 wt% Ti - 0.07 wt% Nb) and X80 (0.04 wt% C - 0.025 wt% Ti - 0.09 wt% Nb) steels, where the numbers refer to their specified minimum yield strength (SMYS) in ksi. This class of steels has the advantage of high strength and good toughness combined with minimal wall thickness (15.5 mm for X70 steel). These attributes result in considerable cost savings when installation of several hundreds of kilometers of pipeline is required for oil and natural gas recovery and transport. The present study focused on phase identification and quantification, distribution of alloying elements and inclusions and segregation effects. Both steels were primarily composed of a mixed ferrite structure, i.e., polygonal ferrite and acicular ferrite/bainite, with characteristic low angle grain boundaries and high dislocation densities. The proportion of acicular grains was higher for the X80 steel. Pockets of retained austenite, exhibiting a Kurdjumov-Sachs orientation relationship (KS-OR) with the adjoining ferrite, were found in both steels. Five general classes of precipitates were identified in both steels: 1) Very large (2–10 μm) cuboidal TiN particles nucleated on inclusions; 2) large (0.1–1.0 μm) cuboidal TiN particles; 3) medium sized (30–50nm), irregular shaped Nb-Ti carbonitrides; 4) fine (<20nm), rounded precipitates of Nb carbonitrides with traces of Mo; 5) very fine dispersed precipitates (<5 nm in size). For X80 steels many of the large TiN precipitates were observed with Nb-rich carbonitrides precipitated epitaxially on them. Inclusion content and morphology were analyzed in both steels. The inclusions in X70 steels were found to be primarily CaS with significant amounts of Al, O, Ti, Fe and Mn. They were essentially spherical in shape with small elliptical distortions along the rolling direction and across the width of the plate. The morphology of the inclusions in the X80 steel was very similar, however, they showed higher Mn levels.

Abstract:
Abstract The effects of Cr and W on the creep rupture life of 8.5-11.5Cr steels at 650°C were evaluated. Throughout this paper the specimen composition is expressed in mass percent. The creep rupture life of 8.5Cr steel is the longest in 8.5-11.5Cr steels at 650°C under the stress of 78MPa. The creep rupture life of 9Cr steel at 650°C was extended with increasing W content. The creep strength of the modified steel, 9Cr-4W-3Co-0.2V-NbBN steel, at 650°C did not decrease sharply up to 32000h. The 105h creep rupture temperature of this steel under the stress of 100MPa was estimated to be approximately 635°C using Larson-Miller parameter. M23C6 type carbides and VX type carbonitrides were observed on the lath boundary of the modified steel. The stability of these precipitates in the modified steel is likely to suppress the degradation of the long term creep strength at 650°C.

Abstract:
Abstract Microstructure in the gage sections of ruptured GX12CrMoWVNbN10-1-1 cast steel specimens was examined after creep tests under applied stresses ranging from 120 to 160 MPa at T=893 K. The microstructure after tempering consisted of laths with an average thickness of 332 nm. The tempered martensite lath structure was characterized by M23C6-type carbide particles with an average size of about 105 nm, and MX carbonitrides with an average size of about 45 nm. Precipitation of Laves phase occurred during creep test. The structural changes in the gauge section of the samples were characterized by the evolution of relatively large subgrains with remarkably lowered density of interior dislocations within former martensite laths. MX carbonitrides and M23C6-type carbide particles increase in size slightly under long-term creep. Microstructural degradation mechanisms during creep in GX12CrMoWVNbN10-1-1 cast steel are discussed.

Abstract:
Abstract Vanadium microalloying additions are common in medium carbon ferrite-pearlite steel shafts. The increased load capacity provided by vanadium carbonitride precipitation is beneficial in many applications. Induction hardening can further increase the surface strength of a component; however, the implications of the vanadium carbonitride precipitates on microstructural evolution during induction hardening are unclear. Evidence that vanadium microalloying influences the microstructural evolution of the induction hardened case as well as the case/core transition regions are presented in the current study. Vanadium increases the amount of non-martensitic transformation products in the case while decreasing austenite formation kinetics in the case/core transition region. Observations in induction-hardened shafts were supported by Gleeble physical simulations of computer simulated thermal profiles. Characterization was conducted using scanning electron microscopy, dilatometry, and microhardness testing.

Abstract:
In this paper, the microstructure of 9%Cr steel 10Cr9MoW2VNbBN under different heat treatment or creep testing was investigated. The morphology of tempered martensite microstructure varies after different heat treatment. After the creep test at 620°C or 650°C, the martensite lath microstructure kept unchanged, although the amounts and the sizes of precipitates, such as the carbides M23C6, carbonitrides MX, and Laves phase, increased with the creep time. The martensite laths microstructure morphology changed after the creep test at 700°C, with the carbides coarsened severely at grain boundaries. Paper published with permission.

Abstract:
Abstract This work concerns a study into the design of creep resistant precipitation hardened austenitic steels for fossil fuel power plants using an integrated thermodynamics based model in combination with a genetic algorithm optimization routine. The key optimization parameter is the secondary stage creep strain at the intended service temperature and time, taking into account the coarsening rate of MX carbonitrides and its effect on the threshold stress for secondary creep. The creep stress to reach a maximal allowed creep strain (taken as 1%) at a given combination of service temperature and time is formulated and maximized. The model was found to predict the behavior of commercial austenitic creep resistant steels rather accurately. Using the alloy optimization scheme three new steel compositions are presented yielding optimal creep strength for various intended service times up to 105 hours. According to the evaluation parameter employed, the newly defined compositions will outperform existing precipitate strengthened austenitic creep resistant steels.

Abstract:
Abstract A software simulation tool, CarbonitrideTool, has been developed by Center for Heat Treatment Excellence (CHTE) to predict the Nitrogen and Carbon concentration profiles in selected steels. In this paper, the introduction of the software will be presented. In addition, enhancements have been made to improve the CarbonitrideTool. The diffusion of nitrogen increases the amount of retained Austenite (RA) by changing the Ms temperature. In this paper, the modification has been made to calculate the RA fraction. The empirical prediction of microhardness profile will also be presented. The results of verification experiments will be presented and discussed.

Abstract:
An Fe-Cr-W-V-Ti-N steel named SCRAM (super-clean reduced-activation martensitic) steel was designed for the first wall and blanket structure of fusion power plants. Compared with the Fe-Cr-W-V-Ta steel, TiN can precipitate first at 1650°C rather than TaC by the Thermal-cal Calculation. And we take vacuum induction melting (VIM) and electro-slag re-melting (ESR) together to manufacture the SCRAM steel, which can make the TiN fine and the steel pure. Mechanical properties and microstructures of SCRAM steels irradiated with single-beam (Fe) and sequential-beam (Fe plus He and Fe plus H) at 300°C were studied. The results show that, SCRAM steel can have better mechanical properties before and after irradiation while Ti was doped into the SCRAM steel. It has been reported that the precipitation formed in the steel has effect on the mechanical properties, irradiation properties and the ductile brittle transition temperature (DBTT). The effect of intermediate heat treatment on precipitation behavior and mechanical properties of SCRAM steel was investigated in order to obtain dispersed fine M23C6 carbides. The results indicated that MX carbonitrides precipitated first in the steel with intermediate heat treatment at 870°C rather than M23C6, which led to a decrease of carbon concentration in the supersaturated martensitic matrix and correspondingly a reduced volume fraction and mean size of M23C6. The intermediate heat treatment was beneficial to the mechanical properties, and proposed for reduction on the ductile brittle transition temperature (DBTT).

Abstract:
Abstract In order to clarify the effect of stress state on microstructural changes during creep, the microstructure was observed in the central part of the cross section of the fine-grained heat-affected zone (FGHAZ) and in the surface region of the FGHAZ in Gr.92 steel welded joint. Creep tests were performed under constant load in air at 650°C, using cross-weld specimens. The creep strength of welded joint was lower than that of base metal. Type IV fracture occurred in the long-term. Creep voids were detected in the FGHAZ after the fracture. Number of creep voids was higher in the central part of the cross section of the FGHAZ than in the surface region of the FGHAZ. It was checked the multiaxiality of stress during creep was higher in the central part of the cross section of the FGHAZ than in the surface region of the FGHAZ. The recovery of dislocation structure occurred after creep in the base metal and the FGHAZ. Mean subgrain size increased with increasing time to rupture. However, there was no difference of change of subgrain size during creep in the central part of the cross section of the FGHAZ and in the surface region of the FGHAZ. The growth of M23C6 carbide and MX carbonitrides was observed during creep in the base metal and the FGHAZ. Laves phase precipitation occurred during creep. There was no difference of the change of mean diameter of MX carbonitrides in the central part of the cross section of the FGHAZ and in the surface region of the FGHAZ after creep. However, the growth rate of M23C6 carbide in the FGHAZ was much higher in the central part of the cross section than in the surface region.
