Abstract:
Abstract Magnesium alloy has extremely excellent properties and is known as “21st Century Green Engineering Material”. This article mainly introduces the influence of the heat resistance and comprehensive performance of the three series of Mg-Al, Mg-Zn and Mg-RE heat-resistant magnesium alloys after adding rare earth elements, alkali metal elements and other elements. Three development directions of improving the heat resistance of magnesium alloys are prospected. These are: 1. Using cheap alloy elements (such as Ca, Si, etc.) to replace rare earth elements of the heat-resistant magnesium alloy, 2. Titanium element is added to improve heat-resistant magnesium alloy’s mechanical properties and its strength, 3. The new casting process and processing technology are used to improve the heat-resistant magnesium alloy’s properties. This article aims to provide technical reference for the development of my country’s magnesium alloy industry.

Abstract:
Main properties and structure of 2 mm thick sheets and 20×100 mm extruded strips made under industrial conditions from Al-Cu-Mg heat-resistant B-1213 alloy with Ag, Cr, Mn and Zr additions were investigated. It was stated that wrought B-1213 alloy semiproducts are superior to analogous semis made of widely used commercial heat resistant AK4-1ch-type alloys (analogues - AU2GN, 2618 alloys) in strength properties and heat resistance characteristics (by 10-20 %) as well as in crack resistance and fatigue life (by 20-40 %). B-1213 alloy is intended for replacement of traditional heat-resistant alloys of system Al-Cu-Mg-Fe-Ni in advanced aircraft primary structure components subjected heating at elevated temperatures (up to 200-250 oC) and allows one to increase weight efficiency, service life and reliability.

Abstract:
Alloy selection and alloy design both require consideration of an array of material attributes, including in-service properties, weldability, and fabricability. Critical properties of modern heat-resistant alloys for gas turbine applications include high-temperature strength, thermal stability, oxidation resistance, and fatigue resistance. In this paper, the properties of 12 solid-solution-strengthened and six age-hardenable heat-resistant alloys are compared. Weldability is an important attribute and can be a major limiting factor in the use of certain alloys. Weldability test methods are discussed, and the resistance of alloys to solidification cracking and strain-age cracking is compared. The use of weldability testing in the development of modern heat-resistant alloys is discussed with several examples cited. Finally, alloy selection for gas turbine components is outlined, taking into account both alloy properties and fabricability.

Abstract:
Currently, an important fundamental problem of practical importance is the production of high-quality solid-phase compounds of various metals. This paper presents a theoretical model that allows one to study the diffusion process in nickel-base refractory alloys. As an example, a two-dimensional model of ternary alloy is considered to model diffusion bonding of the alloys with different compositions. The main idea is to divide the alloy components into three groups: (i) the base element Ni, (ii) the intermetallic forming elements Al and Ti and (iii) the alloying elements. This approach allows one to consider multi-component alloys as ternary alloys, which greatly simplifies the analysis. The calculations are carried out within the framework of the hard sphere model when describing interatomic interactions by pair potentials. The energy of any configuration of a given system is written in terms of order parameters and ordering energies. A vacancy diffusion model is described, which takes into account the gain/loss of potential energy due to a vacancy jump and temperature. Diffusion bonding of two dissimilar refractory alloys is modeled. The concentration profiles of the components and order parameters are analyzed at different times. The results obtained indicate that the ternary alloy model is efficient in modeling the diffusion bonding of dissimilar Ni-base refractory alloys.

Full text
Abstract:
Metal dusting leads to disintegration of such alloys as iron and nickel-based into a “dust” of particulate metal, metal carbide, carbon, and/or oxide. It occurs in strongly carburising environments at 400-900°C. Literature survey has shown that alloys behave differently in metal dusting conditions based on their composition and the environment. Metal dusting mechanisms for iron and nickel-based alloys have been proposed but, nevertheless, have not been agreed upon and numerous modifications to them have been suggested. Further adding to the complexity, the mechanisms were found to have differed due to operating condition alterations. In view of that, this research was carried out to gain a better understanding of metal dusting process(s) by evaluating the performance of heat-resistant alloys, namely KHR35C HiSi© (HP), KHR45A LC© (35Cr-45Ni), and UCX©, in metal dusting conditions. HP, which is an iron-based alloy, was modified by adding more silicon in order to improve its resistance through the development of SiO2 at the surface. The carbon content in the nickel-based alloy, 35Cr-45Ni, was lowered to delay the attack onset by accommodating more diffused carbon. UCX©, however, has the highest nickel and chromium levels. The alloys were exposed to a gas containing 80 vol% CO+20 vol% H2 at 650, 750, and 850ºC for 100, 500, and 1000h. Analyses including visual inspection, XRD, and SEM/EDX revealed that the alloys suffered localised attacks at the three temperatures but to varying degrees and in different shapes. In general, the attack initiated at the matrix rather than the primary carbides and also progressed through the matrix. Increasing the exposure temperature caused less carbon deposition and more oxides formation on the alloy surfaces leading to a reduction in the attack aggressiveness. UCX© exhibited the highest resistance to metal dusting whilst HP suffered the severest attack. The presence of high concentrations of chromium at the surface catalysed a quick formation of Cr2O3 scale that reduced the extent of metal dusting. Also, the increase in nickel content might have slowed down the carbon diffusion into the alloy. In addition, the presence of other oxide and carbide-forming elements such as silicon and tungsten might well have enhanced the alloy performance. Diffused carbon binds with free tungsten, niobium, and chromium to form carbides prolonging the incubation period prior to the attack initiation.

Abstract:
Atlas Copco is interested in investigating the friction in the top-hammer drilling tool threads thatcauses the steel to heat up, leading to a phase transformation and a softer steel in the threads. Theaim of this project is to find a steel alloy or surface finishing that will retain its hardness atelevated temperatures better than the presently used threads material. The solution is intended tobe used as a replacement material for the threads. The potential material is meant to combat thepremature breakdowns of the threads and thus minimizing the economical losses. To achieve ourproject goal, literature studies and an experimental parts were employed.Hardening methods are discussed thoroughly in the thesis, such as carbides/nitrides,precipitation, solid solution, grain size, and martensitic transformation. Alloying elements andtheir effects on steels properties were also discussed. C, Cr, Co, Mn, Mo, Ni, W, and V werefound to increase the steel's hardness at elevated temperature, high temperature strength andabrasion wear resistance.Nitration can be applied to most of the steels that Atlas Copco uses today, and will give a harder,and more wear resistant surface at elevated temperatures. A problem with nitration is that thenitrided layer is generally thinner than the martensitic hardening used today.Three tool steels samples (ASP 2030, ASP 2053 and ASP 2060) were acquired from Erasteel.These were used in the experimental part and compared to reference steels that Atlas Copcocurrently are using (R1-R6). The experiments were conducted in 400 and 600°C and the sampleswere tempered for 1, 10 and 100 hours before the hardness were measured with a Vickershardness test. The conclusion from the experiments was that ASP 2060 and ASP 2053 fromErasteel are the steels that have a much higher hardness at elevated temperature than the othersteels tested in the experiment. The results indicate that the tool steels will probably notexperience the same premature breakdown as the threads used today. R1 and ASP 2053 have thegreatest heat resistance.The suggested tool steels are all quite expensive, and to minimize the material needed only thethreads and not the rod can be in the new alloy. Lowering the cost could also be achieved byhardfacing where a layer of the new expensive alloy is welded onto a cheaper steel.

Abstract:
Heat resisting centrifugally cast tubes of HP micro alloy (25/35 Cr/Ni, 0.4C), are extensively used in steam reforming, which is currently the dominate technology for hydrogen generation. High pressure of the reacting gases inside the tubes generates high hoop stress in the tube wall and together with the temperature exposure of 900-1050°C causes the tubes to creep along the circumferential direction. The alloy's ability to successfully withstand the severe operating condition is highly dependent on its high temperature creep-rupture behaviour. In recent years a number of manufactures have introduced higher creep-rupture strength versions of the heat resisting HP micro alloy. As a consequence they are able to offer the centrifugally cast tubes in thinner walls. Therefore, there is a need to enhance the creep-rupture strength of the alloy produced by Doncasters Paralloy. The immediate objective of this research project is to establish the mechanisms that govern the creep process in this alloy system. Once these mechanisms are better understood further alloy development within the present alloy composition can be achieved. The advanced stages of the project specifically involve studying the influence of microstructure in relation to creep resistance as a function of compositional modifications.

Abstract:
Advanced heat resistant materials are important to achieve the transition to long term sustainable power generation. The global increase in energy consumption and the global warming from greenhouse gas emissions create the need for more sustainable power generation processes. Biomass-fired power plants with higher efficiency could generate more power but also reduce the emission of greenhouse gases, e.g. CO2. Biomass offers no net contribution of CO2 to the atmosphere. To obtain greater efficiency of power plants, one option is to increase the temperature and the pressure in the boiler section of the power plant. This requires improved material properties, such as higher yield strength, creep strength and high-temperature corrosion resistance, as well as structural integrity and safety. Today, some austenitic stainless steels are design to withstand temperatures up to 650 °C in tough environments. Nickel-based alloys are designed to withstand even higher temperatures. Austenitic stainless steels are more cost effective than nickel-based alloys due to a lower amount of expensive alloying elements. However, the performance of austenitic stainless steels at the elevated temperatures of future operation conditions in biomass-red power plants is not yet fully understood. This thesis presents research on the influence of long term high-temperature ageing on mechanical properties, the influence of very slow deformation rates at high-temperature on deformation, damage and fracture, and the influence of high-temperature environment and cyclic operation conditions on the material behaviour. Mechanical and thermal testing have been performed followed by subsequent studies of the microstructure, using scanning electron microscopy, to investigate the material behaviours. Results shows that long term ageing at high temperatures leads to the precipitation of intermetallic phases. These intermetallic phases are brittle at room temperature and become detrimental for the impact toughness of some of the austenitic stainless steels. During slow strain rate tensile deformation at elevated temperature time dependent deformation and recovery mechanisms are pronounced. The creep-fatigue interaction behaviour of an austenitic stainless steel show that dwell time gives shorter life at a lower strain range, but has none or small effect on the life at a higher strain range. Finally, this research results in an increased knowledge of the structural, mechanical and chemical behaviour as well as a deeper understanding of the deformation, damage and fracture mechanisms that occur in heat resistant austenitic alloys at high-temperature environments. It is believed that in the long term, this can contribute to material development achieving the transition to more sustainable power generation in biomass-red power plants.

Abstract:
Solid oxide fuel cells operate at elevated temperature, oxidising fuel gases to generate electricity. The fuel gas streams in the fuel cell systems are rich in carbon and have very low oxygen potential. Under these conditions, alloys can undergo metal dusting, which causes pitting or general thinning of the alloys. This process is not yet fully understood. It is, hence, not possible to accurately predict the susceptibility of a particular alloy in the atmospheres relevant to SOFC. Model Fe-Cr and Fe-Ni-Cr alloys were exposed to test the hypothesis that cementite formation and its decomposition is necessary for metal dusting to occur. A series of ferritic and austenitic engineering alloys were also exposed to compare their dusting rates. Two specimens of each alloy were studied, one was etched in a H3PO4-15%H2SO4-21%H2O solution and the other was ground to a 600-grit finish. The alloys were exposed to a CO-26%H2-6%H2O gas mixture at 680oC under thermal cyclic conditions. The hot gas composition corresponded to ac = 2.9 and an oxygen potential high enough to oxidise chromium, but not iron or nickel. All the alloys were shown to undergo internal carburisation, metal dusting and coking once the protective chromium oxide scale was damaged. Fe-25Cr was less resistant than Fe-60Cr because of its lower chromium content. However, ferritic Fe-25Cr-based steels are more resistant to dusting than austenitic Fe-25Cr-25Ni. The present findings are consistent with the earlier conclusions that cementite formation is essential for dusting on ferritic steels and that dusting of austenitic alloys does not involve the prior formation of cementite and its decomposition. The onset of metal dusting was more accelerated for most austenitic engineering alloys (Alloy 800, Inconel 601, 690, 693 and Alloy 602CA) than for engineering ferritic steels (Fe-27Cr-0.001Y). However, the alloy with the best performance was austenitic Inconel 625, which was still protected by its Cr2O3 scale after 500 one-hour cycles. In both ferritic and austenitic chromia-formers alloys, the surface ground specimens were more resistant to metal dusting than the electropolished specimens. In contrast, ferritic alumina-formers with electropolished surfaces did not dust during the entire experimental periods of 1200 one-hour cycle, but the alloys with ground surfaces slowly underwent dusting attack. The coke deposits formed consisted largely of graphite nanotubes, containing small particles at the tube tips. These particles were identified as single crystal cementite, in the case of ferritic steels, and austenite, for the austenitic alloys. This is not in agreement with the currently accepted dusting model for ferritic steels that cementite decomposition yields iron particles, which catalyse coke deposition. EDX analysis of the cementite particles, showed that the only metal detected was iron, thus differing in chemistry from the (Fe,Cr)3C surface layer. Similarly, the austenite particles contained only nickel and iron, differing in chemistry from the disintegrated alloy surfaces. These results suggested that the particles were formed in the coke in the carbon-supersaturated gas, rather than disintegration of the alloy surface layer. Strong orientation relationships were determined between the graphite and cementite particles; however, no clear crystallographic relationship was deduced between the graphite and austenite. Relative alloy performance appears consistent using the present multiple one-hour cycle and the results of others using a smaller number of lengthy cycles. Hourly thermal cycling was shown to accelerate the dusting onset for both electropolished chromia-formers and surface ground alumina-formers. Protective oxide scales spall at a critical thickness and carbon attack results when the alloy surfaces are depleted of scale-forming elements and healing becomes impossible. On this basis, analytical models were developed and used to predict the incubation periods for oxide failure and the subsequent carbon attack. Upon testing, these models were, however, found to be not qualitatively meaningful in predicting the onset of dusting observed in the present study. Gross oversimplifications involved in the model and the absence of reliable data for many parameters required for the computations prevented even an approximate quantitative prediction.

Abstract:
The main aim has been to investigate the effect of process parameters on the spray forming of UDIMET 720 and in particular to understand the mechanism of grain size evolution in the deposit using a combination of experimental and computer modelling techniques. Samples of two spray formed Ni superalloys, MAR-M-002 and UDIMET 720, have been re-heated into the solid/liquid region and the fully solid region just below the solidus temperature for a series of times to try and reproduce the situation of grain growth in a spray formed deposit. Grain growth in the solid/liquid region follows the equation: d3=d03 +Kt, where d is the grain size, d0 is the initial grain size, K is the coarsening rate constant and t is the time. Coarsening rate constants have been determined for temperatures in the solid/liquid region and they increase with increasing temperature/decreasing solid fraction. Existing spray forming equipment for Al alloys has been modified to manufacture UDIMET 720 deposits. Process conditions were monitored continually during spray forming, in particular the temperature of the deposit by embedded thermocouples and infra red thermal imaging of the deposit top surface. Above a deposit temperature of ≈1250°C the microstructure consists of equiaxed fine grains (20μm-35μm) and the porosity is low (<1%). Below this deposit temperature the microstructure consists of droplet "splats" and the porosity is higher (2-4%). The measure grain size increases with increasing deposit temperature and solidification time and agrees reasonably well with the predicted grain size using the above equation. A commercial finite difference based fluid dynamics software program, FLUENT, has been used to model the 2-dimensional dynamic and thermal behaviour of UDIMET 720 droplets during gas atomisation and spray forming. The effect of atomising gas pressure, spray distance and melt mass flow rate on the equilibrated droplet spray temperature has been examined and shows similar variations with process parameters as the measured maximum deposit temperature. The predicted spray temperature at the substrate is always higher than the measured maximum deposit temperatures under all conditions, and increases with (i) decreasing gas pressure, (ii) decreasing spray distance and (iii) increasing MFR. Mean droplet temperatures and velocities are strongly dependent on droplet size, the mean droplet temperature decreases and mean droplet axial velocities increases with decreasing droplet size.

Abstract:
Alloy selection and alloy design both require consideration of an array of material attributes, including in-service properties, weldability, and fabricability. Critical properties of modern heat-resistant alloys for gas turbine applications include high temperature strength, thermal stability, oxidation resistance, and fatigue resistance. In this paper, the properties of twelve solid-solution-strengthened and six age-hardenable heat-resistant alloys are compared. Weldability is an important attribute, and can be a major limiting factor in the use of certain alloys. Weldability test methods are discussed and the resistance of alloys to solidification cracking and strain-age cracking is compared. The use of weldability testing in the development of modern heat-resistant alloys is discussed with several examples cited. Finally, alloy selection for gas turbine components is outlined, taking into account both alloy properties and fabricability.

Abstract:
Cast heat resistant alloys are used in the petrochemical industry for reformer furnace tubes and ethylene pyrolisis coils. These alloys have traditionally been developed through the casting of trial compositions with differing additions of alloying elements followed by long term (10,000 hour) stress to rupture testing. It is now possible to shorten the development process through the use of computational thermodynamics and a detailed understanding of composition, microstructure and property relationships. This paper will provide examples of how alloys can be developed through a combination of thermodynamic modeling, microstructural characterization, and mechanical property measurements.

Abstract:
Abstract NiAl precipitates with the B2 structure are known to be effective in increasing the strength of ferritic heat-resistant steels. The strengthening mechanism by the NiAl precipitates was examined using Fe-21Al-2Ni and Fe-23Al-6Ni (at%) single crystals. As a result, the difference in primary slip system between the bcc matrix and the NiAl precipitates is responsible for strong hardening. The B2-NiAl phase was precipitated in the bcc matrix satisfying the cube-on-cube orientation relationship with small misfit strain. The primary slip direction of the bcc matrix and the NiAl precipitates are &lt;111&gt; and &lt;001&gt;, respectively. However, in the ferritic alloys, the NiAl precipitates were cut by paired 1/2&lt;111&gt; dislocations in the bcc matrix, resulting in the hardening. The size and volume fraction of the NiAl precipitates strongly influenced the strength. The stress increase by the NiAl precipitates was also discussed quantitatively based on the precipitation hardening theory. Based on the experimental results obtained by the single crystal study, we developed Fe-Al-Ni-Cr-Mo ferritic heat-resistant alloy containing the NiAl precipitates. The alloy exhibited excellent creep properties at 923 K.

Full text
Abstract:
Pipeline failure due to corrosion is a common problem in the oil and gas and petrochemical industry. A cost-effective way to prevent these failures is the application of corrosion-resistant weld overlays (WOLs) onto the internal surface of line pipe. A WOL is a deposition of a filler metal - such as a nickel-base alloy - onto the surface of a part - usually carbon or low alloy steels - to introduce desired surface properties to the original substrate [1]. As such, the service life of the substrate is increased which results in reduced costs to industries such as oil and gas and petrochemical as well as to the environment. WOLs are commonly created using arc welding processes such as cold wire and hot wire gas tungsten arc welding (CW-, HW-GTAW), gas metal arc welding (GMAW), and submerged arc welding (SAW). Previous research performed at OSU indicates that a low heat input GMAW process, such as cold metal transfer (CMT), can produce WOLs which corrode up to ten times slower than overlays produced with CW-GTAW [2, 3], with up to four times higher deposition rates [4]. However, the majority of research into WOLs produced with the CMT process has been done with respect to nuclear applications, so there is a need for process optimization directed towards oil and gas applications. This project investigates the potential of CMT as an alternative to HW-GTAW for use with nickel-base alloys 625, 686 and 825 clad onto low alloy steel X65.

Abstract:
Since the 1970s, the development of high-strength pipeline steels has followed the route of progressively reduced harden ability through lower carbon and alloying element contents. Micro-alloying, controlled rolling (CR), and thermo-mechanical controlled processing (TMCP) have been used extensively to achieve the high-strength and other material property requirements despite the trend towards lower carbon content. The primary driving force behind the evolution of these alloying and processing strategies stems from the concerns over the weld ability, particularly the hydrogen induced cracking (HIC), at ever-increasing strength levels. Accompanying the extensive reliance on micro-alloying, CR, and TMCP, there has been a movement to tighter restrictions on micro-alloy variability, the increased use of heavy reduction at low inter-critical temperatures and, in some instances, the reliance on cold expansion. The objective of this project was to evaluate alternate steels with enhanced harden ability and identify those that would have a potential to (1) meet the high strength/high toughness requirement but without the adverse effects of the early trial heats of micro-alloyed TMCP X80 and X100 line pipe steels, and (2) exhibit sufficient resistance to hydrogen induced cracking (HIC) when welded with processes and consumables representative of state-of-the-art, low-hydrogen field girth welding practices. The focus of the project was on the weld ability and properties of the base metal and the heat-affected zone (HAZ). The selection and development of suitable weld consumables were not part of this project.
