Summary: The porosity in BJP 316L stainless steel (SS) was reduced from 3.5-5.6% to 1-1.2% by improving process parameters and employing the post-processing hot iso-static pressing (HIP) treatment. The reduced porosity resulted in improved tensile yield and ultimate tensile strengths, but did not improve the high cycle fatigue strength. HIP further reduced the porosity and improved the elongation to failure, but did not improve the unnotched fatigue strength. The microstructural coarsening during HIP affected the short fatigue crack growth resistance of the BJP 316L SS specimens.

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 deformation mechanisms of neutron-irradiated 304 L stainless steel were investigated using the in-situ electron backscattered diffraction (EBSD) technique. Comparative analysis with non-irradiated samples showed that the irradiated samples had higher fractions of slip bands even at low amounts of deformation. Additionally, formation of twins and martensite in the neutron-irradiated samples was found to be almost parallel to the slip bands.

Summary: The hierarchical microstructure produced by L-PBF plays a key role in the superior mechanical properties, particularly the fine cell microstructure with heterogeneous distribution of dislocation density and alloying elements. While previous studies focused on the effect of this structure on monotonic loading, this study provides insight into the cyclic behavior of L-PBF processed metastable austenitic stainless steel 304L and its relation to microstructure evolution and strain-induced martensitic transformation.

Summary: MYRRHA is an accelerator driven system using liquid Lead-Bismuth eutectic alloy as a spallation target and coolant. Although nuclear grade austenitic stainless steels are selected as main candidate structural materials, some materials exhibit unexpectedly poor mechanical properties due to the presence of intermetallic a-phase. In-depth microstructural analysis is necessary to identify and address this issue in order to prevent misinterpretation of embrittlement in the austenitic matrix.

Summary: The study investigates how constrained groove pressing (CGP) affects the microstructural evolution and mechanical properties of 304 austenitic stainless steel. CGP significantly improves mechanical properties such as tensile strength and micro-hardness. XRD analysis and finite element analysis confirm the transformation of austenite phase into martensite phase, decrease in crystallite size, increase in microstrain, and increase in dislocation density due to CGP.

Summary: Friction surfacing is a solid-state deposition process that offers improved microstructural and mechanical properties compared to fusion-based deposition methods. The study investigates the microstructure and corrosion properties of friction-surfaced 304L stainless steel consumable rods on 304L stainless steel substrates. The results show that friction surfacing produces a fine-grained microstructure with distributed strain-induced martensite and high residual compressive stresses, which can mitigate pitting corrosion and potentially chloride-induced stress corrosion cracking (CISCC).

Summary: The study explored the electrochemical corrosion response and tribological behavior of 304L and 316L stainless steel welded by gas metal arc welding (GMAW). The results showed that 316L steel exhibited better wear performance, lower coefficient of friction, and lasting durability compared to 304L stainless steel due to the higher presence of molybdenum and chromium.

Summary: 316L austenitic stainless steel with heterogeneous structure and excellent strength-ductility synergy was fabricated through cold rolling and subsequent annealing. The heterogenous structure consisted of austenite, martensite, and twins, with finegrain strengthening and back stress hardening contributing to its strength, and heterogeneous deformation-induced strain hardening contributing to its ductility.

Summary: The microstructure development of 316 LN austenitic stainless steel during aging process was investigated. It was found that the presence of twins in the grains decreased as the aging period increased. Precipitation of fine particles from the matrix occurred after 50 hours of aging and were identified as M23C6. The aging process also affected the impact toughness and Brinell hardness, and a negative linear relationship between Brinell hardness and Charpy impact energy was established to predict thermal embrittlement.

Summary: The stored energy induced by SLM process and cyclic strain during fatigue testing can trigger grain boundary migration and local recrystallization behavior, impacting the fatigue performance of stainless steel. Understanding the role of local recrystallization in fatigue failure mechanisms of additively manufactured materials is essential for further research and development in this field.
