Lamari, Mathias. "In situ characterization and modelling of retained austenite thermomechanical stability in Medium Manganese Duplex TRIP-aided steels". Electronic Thesis or Diss., Université de Lorraine, 2023. http://www.theses.fr/2023LORR0114.
Texto completo da fonteMedium manganese steels belong to the so-called 3rd generation of Advanced High Strength Steel (AHSS). Their ground-breaking properties are due to their particular duplex microstructures, which contain a micrometric “ferritic” matrix and a large amount of retained austenite. This new generation of steels is seen as one of the best possibilities for carmakers to continue improving the safety of light-duty vehicles and reduce their energy consumptions² and thus their environmental footprints. The good formability and the high resistance of those steels are explained by the strain-induced martensitic transformation (SIMT) of residual austenite during a mechanical loading. The gradual transformation of ductile austenite into high strength martensite causes a rapid increase in the macroscopic work-hardening of the steel, mechanism known as Transformation Induced Plasticity effect (TRIP). Understanding and modelling the stability of retained austenite and the related mechanical response of these steels are thus of great interest both from a scientific and industrial point of view.For this purpose, eight different microstructures have been designed based on thermodynamical calculations in order to evaluate the respective effect of the morphology, the composition and the grains size on austenite stability. The formation of the duplex microstructures during intercritical annealing have been characterized in situ by high-energy X-ray diffractions (HEXRD) experiments on synchrotron beamline. In addition to measuring austenitization kinetics using Rietveld refinements, these experiments reveal in an original way the mechanisms of primary precipitation/dissolution of carbides during heating and the large residual hydrostatic stresses at the scale of the phases obtained after final cooling. The origin of these latter has been explained and quantified through a model. An extensive scanning electron microscopy (SEM) and Castaing microprobe work was also conducted to measure the sizes and chemical compositions of the different microstructure components.The tensile mechanical behaviour of the studied steels has been measured in combination with HEXRD experiments and Digital Image Correlation (DIC) measurements. These unique in situ experiments permit to measure simultaneously the SIMT kinetics, the 3D stress partitioning between phases (namely ferrite, austenite and martensite) using sin²ψ methods and the local strains all along the tensile specimens. These latter serve in particular to characterize Lüders and Portevin-Le Chatelier (PLC) bands which affect the studied medium Mn steels.All those experimental inputs have served to develop an innovative mean field micromechanical framework to predict the tensile behaviour of medium Mn steels with austenite-ferrite-martensite microstructures. It relies on the description of the local behaviours of each constituting phase and of the SIMT of retained austenite, both calibrated on our HEXRD experiments. The work-hardening of austenite and ferrite are modelled thanks to a size-sensitive model based on dislocation densities. The behaviour of fresh and strain induced martensite is considered on the contrary as an extended elastic/plastic transition. The SIMT kinetics is based on a thermodynamical assessment of the stability of retained austenite inspired by Olson and Cohen pioneering work. The model is thus finally sensitive to the size of the microstructure components, to their local composition and to their respective stability and it shows an excellent agreement with the experimental observations

Texto completo da fonteDuring the intercritical annealing of fully martensitic Medium Mn steel, containing from 4 to 12 wt.% Mn, the formation of austenite happens through the so-called “Austenite Reverted Transformation” (ART) mechanism. In this PhD work, the evolution of both microstructure and tensile properties was studied as a function of holding time in the intercritical domain. The microstructure evolution was studied using a double experimental and modeling approach. The final microstructure contained phases of different natures (ferrite (annealed martensite), retained austenite and fresh martensite) and of different morphologies (lath-like and polygonal). A particular attention was paid to the kinetics of austenite formation in connection with cementite dissolution and to the morphology of the phases. A mechanism was proposed to describe the formation of such microstructure. The critical factors controlling thermal austenite stability, including both chemical and size effects, were determined and discussed, based on the analysis of the retained austenite time-evolution. At last, tensile properties of the steel were measured as a function of holding time and the relation between microstructure and mechanical behavior was analyzed. Advanced analysis of the individual behavior of the three major constituents was performed. As a final output of this work, a complete model for predicting the true-stress versus true-strain curves of medium Mn steels was proposed

Texto completo da fonteHigh strength low alloy (HSLA) steels have been widely used in the manufacture of pipelines for the transport of oil and gas. However, the application of these steels in media with high H2S concentrations, denominated sour, has resulted in frequent failures due to the susceptibility of these materials to the development of Hydrogen Induced Cracking (HIC) phenomena, as well as due to corrosion problems. The development of different technological processes for HSLA piping production, like controlled rolling and accelerated cooling, the addition of microalloying elements, as well as the reduction of the amounts of sulphur, phosphorus, carbon and manganese, has led to the development of materials with optimized mechanical properties, also allowing a better microstructural control. Hardness and mechanical resistance reduction due to the lowering of Mn content are compensated by niobium and chromium addition. In this work, the corrosion resistance and the hydrogen permeability parameters of two API 5L X65 steel tubes and an API 5L X65 plate, all HSLA type and with low manganese (0.27%) and high niobium (0.083% to 0.090%) contents, are compared in solution B of NACE standard TM-0284 (2011). For this, open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization curves were carried out in the naturally aerated, deaerated and H2S saturated electrolyte. Hydrogen permeability tests were performed based on ASTM INTERNATIONAL G148-97, but using a modified DEVANATHAN and STACHURSKY (1962) cell and with H2S as cathodic poison. The materials were characterized by means of optical microscopy (OM), scanning electron microscopy (SEM) and X-Ray Energy Dispersive Spectroscopy (EDS) prior and after immersion tests in the different electrolytes. Characterization of the corrosion products by X-ray diffraction (XRD) was also performed after immersion in the H2S-saturated (sour) medium. The OM and SEM characterization showed ferritic matrices for the three steels, with the presence of low levels of the martensite/austenite (M/A) microconstituent, perlite and with a low level of inclusions evenly distributed and with similar chemical compositions. The results of the corrosion tests showed that, for all investigated media, the steel denominated as B presented the best resistance to corrosion, whereas the one denominated as C showed to be the most susceptible in all the conditions studied. For the three steels, the corrosion resistance showed the following ascending order according to the exposure medium: H2S saturated < naturally aerated medium < deaerated media. OCP and EIS tests in the H2S-saturated medium in a period of 24 hours showed that the corrosion resistance increases over time due to the formation of an iron sulphide layer, which, however, presented little adhesion. The results of the hydrogen permeation tests showed that the steel denominated B, that presented greater corrosion resistance in all media and that does not present perlite in its microstructure, had the highest values of effective hydrogen diffusivity, the lowest concentration of atomic hydrogen in the subsurface and the smallest amount of traps per unit volume. Concerning the other two materials, the results of the permeability tests were at variance with the results of the microstructural characterization and corrosion resistance tests, indicating that factors other than those detected in this study are important to govern such properties.

The current work investigates micro/nanostructure and mechanical behaviors of microalloyed medium-Manganese steels processed by quenching and austenite reversion (Q&AR). Precipitation behaviors of carbides due to complex additions of Ti, V, Nb, and Mo and their roles were compared and discussed in this work. It was found that formation of microalloyed carbide can contribute to materials’ strength in two ways. During austenization, coarser carbides enable significant grain refinement by the Zener pinning effect, leading to finer martensite laths and uniform distribution of reversed austenite in latter processes. During austenite reversion, precipitation of extremely fine carbides enables effective precipitation strengthening. All these benefits compensate the softening due to inter-critical annealing and increase materials yield strength. Moreover, with well-controlled temperature of austenite reversion, optimized ductility can be obtained when volume fraction of retained austenite is maximized. Based on established principles, a Nb-Mo-V-adding steel was designed for optimized mechanical properties: yield strength > 700 MPa, ultimate tensile strength > 1000 MPa, uniform elongation > 14 %, total elongation > 20 %. This thesis demonstrates the novel process and the combination of alloy design to create advanced high-strength steels with excellent properties.

In conventional quenching and partitioning (Q&P) processing, carbon partitions into retained austenite and stabilizes it during partitioning heat treatment at 300-500°C. The current research aimed at developing quenching and high temperature partitioning (Q&HTP) processing, in which manganese and carbon both partitioned into and stabilized retained austenite during high temperature partitioning heat treatment. To achieve this goal, new heat treatment processing and newly-designed alloys were developed. High temperature partitioning accompanied with austenite reversion was carried out at intercritical annealing temperature, producing fine austenite phase uniformly distributed in tempered martensite matrix. However, during intercritical annealing, martensite lath coalescence and dislocation annihilation would reduce the strength of Q&HTP steels. To compensate the softening effect, niobium and vanadium carbides were introduced into newly-designed alloy to enhance strength by grain refinement and precipitation strengthening. In present work, the increments of yield strength due to precipitation strengthening were about 100-200 MPa. Also, the effect of aluminum containing was investigated in this research. The optimum temperature of Al-free and Al-containing Q&HTP steels was 690 °C and 710 °C for 5 min heat treatment. However, the mechanical properties and microstructures of two steels were strongly related to the annealing temperature. The effect of precipitation strengthening in Al-containing steels were about 30-40 MPa higher than in Al-free steels.
