Summary: This study investigates the relationship between deformation-induced martensite (DIM) transformation and variant selection with grain orientation in AISI 316L austenitic stainless steel during uniaxial tensile loading. The combined effect of slip and DIM transformation is comprehensively analyzed using experimental macrotexture analysis, visco-plastic self-consistent simulation, and reconstruction of prior-austenite orientations from electron backscatter diffraction data. The results show that grains with orientations like Brass, Rot-Goss, Rot-Cu undergo plastic deformation by slip and eventually undergo DIM transformation at higher strain levels. Variant selection during DIM transformation is examined using a model based on the phenomenological theory of martensite crystallography, and it is found that variants with higher interaction energies are preferred.

Summary: Grain boundary relaxation can stabilize nanograined structures in many FCC metals and alloys, but this mechanism is interfered by deformation-induced martensitic transformation in 304 stainless steels. In this study, gradient FCC nanograined structures were prepared in a 304 stainless steel and triggered GB relaxation was observed in samples with grain sizes below 60 nm. Thermal stability increased with decreasing grain size, contrary to the conventional trend. Martensitic nanograins of the same composition did not exhibit GB relaxation, as their instability temperature was controlled by reverse martensitic transformation.

Summary: Austenitic stainless steels are widely used for their excellent mechanical and corrosive properties, with 316L ASS known for its great weldability due to low carbon content. Selective dissolution is a significant issue, primarily caused by the significant difference in electrochemical potential between different phases leading to severe austenite corrosion.

Summary: The fatigue crack growth rate of warm-rolled AISI 316 austenitic stainless steel is influenced by rolling temperature and strain, with lower temperature inhibiting crack growth. In the presence of hydrogen gas, the formation of alpha' martensite in warm-rolled specimens is effectively suppressed, leading to a reduction in fatigue crack growth rate.

Summary: The study investigates the microstructure and texture changes of thermomechanically processed 310S austenitic stainless steel. Cryo-rolling with different thickness reductions and subsequent annealing were conducted. Deformation twinning and strain-induced alpha'-martensite were observed after 20% thickness reduction, with higher volume fraction of twinning. With increased deformation, martensite replaced twinning and the volume fraction of martensite increased. Brass, Goss, and S components were dominant textures in the austenite phase, while R-Cu, R-cube, F, and E were the main components in alpha'-martensite. Annealing led to martensite to austenite reversion and recrystallization in the deformed austenite, resulting in increased fractions of Goss and Brass recrystallization components. The annealing texture was similar to the cryo-rolling texture. Martensite reversion was faster at 1223 K for 5 min compared to 1023 K. The optimum annealing temperature for an ultrafine grain structure was found to be 1023 K for 15 min.

Summary: The evolutions of nano-twins and martensitic transformation in 316L austenitic stainless steel during large tensile deformation were studied. The results showed that phase transformation induced plasticity and twinning induced plasticity coexisted during the deformation. Deformation first induced the formation of deformation twins, and dislocation pile-up caused martensitic transformation. With increased deformation, a large number of nano-twins and alpha'-martensite appeared. The width of nano-twins decreased and the frequency of intersecting deformation twins increased. The martensitic transformation could be divided into two types: gamma-austenite -> alpha'-martensite and gamma-austenite -> epsilon-martensite. Alpha'-martensite mainly distributed near the twin boundaries, while epsilon-martensite and stacking faults existed as transition products.

Summary: This study investigates the developed microstructure and tensile behavior of a 316L-type steel produced by selective laser melting. It focuses on the density and arrangement of dislocations, internal distortions, and specific strengthening mechanisms in the steel. The experimental samples were obtained using a 3D selective laser melting system with specific parameters. The results show that the steel has a grain size of 20 μm, a high dislocation density, and a strong fiber texture. The tensile test reveals high yield strength, ultimate tensile strength, and elongation along the side direction. The strengthening mechanisms of solid solution and dislocations contribute to the outstanding strength-ductility combination of the processed steel.

Summary: In this study, the effect of cold rolling on the pitting corrosion resistance of 316L and 304 austenitic stainless steels (ASSs) was investigated using microstructural analyses, electrochemical measurements, and chemical immersion tests. The results showed that cold rolling increased the yield and tensile strength of the stainless steels, decreased the pitting corrosion potentials, and led to the generation of deformation bands that facilitated the formation of pits. Overall, the pitting corrosion resistance of the stainless steels decreased after cold rolling.

Summary: This study investigates the effects of Re and Ta interactions on the precipitation of the TCP phase in experimental alloys under long-term thermal exposure. The study finds that microstructure segregation is not fully eliminated even with standard heat treatment, and the interaction between Re and Ta enhances the formation of the TCP phase. Thermodynamic calculations and first-principles analysis reveal that Re significantly improves the driving force of TCP phase precipitation. The study also observes a phase transition from the sigma-phase to the P-phase, with Ni playing a crucial role in the diffusion process.

Summary: The microstructures and corrosion resistance of TC11 components were significantly improved using a high-power, high-speed laser metal deposition (LMD) process and subsequent post-heat treatment, with greater improvements observed in the deposition direction. The significant improvement of corrosion resistance in the deposition direction is mainly due to the weakening of the charged galvanic corrosion effect between the non-interlayer zone and interlayer zone.

Summary: In this study, the microstructures and mechanical properties of interphase precipitation strengthening micro-alloyed steels were investigated. The addition of Cr was found to increase the yield strength without significant decrease of ductility. Thermodynamics analysis revealed that the addition of Cr led to grain refinement and decrease of sheet spacing of nanoprecipitates. Calculations showed that the decrease of interphase-precipitated carbides sheet spacing and the refinement of grain size were responsible for the strength enhancement of Cr microalloyed steel.

Summary: In this study, bioinspired web-liked multiphase composites were successfully constructed using boron-modified polysilazane polymer. The composites consisted of long TiB nanowires as 'web' and hybrid TiC and Ti3Si particles as 'nodes'. The enhanced strength of these composites was attributed to the synergistic load transfer of the hybrid reinforcements. This study provides a promising design approach for developing high-performance composites with high reinforcement content, utilizing polymer instead of traditional ceramic powder.
