Summary: The effect of post-manufacturing heat treatment on the pitting resistance of directed energy deposition 316L stainless steel was evaluated. The results showed that the heat treatment caused changes in the microstructure of the steel, eliminating the cellular structure and retaining large columnar grains. Both heat treatments significantly improved the pitting resistance of the steel.

Summary: This paper presents a new and scalable electropolishing technique for surface finishing of additively manufactured stainless steel components. The technique is capable of achieving a machined finish surface roughness by removing roughness features greater than 1 μm through the use of pulse/pulse reverse electropolishing. This technique offers more control over the electrodynamic processes and results in higher smoothing efficiency with less material removal compared to conventional direct current electropolishing alone.

Summary: Pillar arrays with sizes of -50-200 nm are created on the surface of 316L material using electrochemical etching. The appearance of nanopillars is attributed to the selective anodic dissolution of dislocation cell walls decorated with high concentrations of Cr/Fe/Ni solute atoms. The pillar arrays extend the passivation range and increase the pitting potential in an HNO3 solution, while reducing the corrosion current density in a NaNO3 solution. The enhanced corrosion resistance is a result of eliminating corrosion-sensitive features and improving hydrophobicity through electrochemical etching.

Summary: This study aims to explore the effects of transformation-induced plasticity (TRIP) induced by cold rolling on AISI 316L grade ASTM F138: 2019, a biomedical material, and its compliance with ISO 5832. Cold rolling of 316L stainless steel is a cost-effective method that provides good surface finish and dimensional accuracy compared to other manufacturing processes. However, the TRIP effect in cold-worked 316L steel can lead to unwanted phases, limiting its use as a biomaterial. Understanding the TRIP effect through cold rolling can enhance its applicability in biomedical engineering.

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: This research investigates the effect of microstructure anisotropy in 316L stainless steel fabricated by laser powder bed fusion on its spall failure and properties. It is found that spall failure tends to initiate at melt pool boundaries and is heavily influenced by the orientation of the impact direction relative to the build direction. The spall behavior is more complex in samples impacted perpendicular to the build direction due to the orientation of microstructural features.

Summary: This research investigates the effects of mechanical shot peening and TiAlCuN coating on additively manufactured 316L stainless steel. Shot peening increases surface hardness by 40%, and the combined effect with coating increases it three-fold compared to as-printed coupons. Shot peening also improves surface finish and induces compressive residual stress. Scratch testing shows better performance in hybrid treated samples, while corrosion tests demonstrate the superiority of the hybrid treated samples over other variables.

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 corrosion behavior of single-crystalline-like stainless steel produced by laser powder bed fusion (LPBF) was investigated and compared with polycrystalline and wrought counterparts. LPBF samples exhibited better corrosion resistance and higher pitting corrosion potential than wrought SS316L samples. These findings provide insights into tailoring the crystallographic texture of LPBF-SS316L to improve its corrosion performance.

Summary: This study investigated the influence of parent austenite grain refinement on the intervariant boundary network in a lath martensitic steel. It found that refining the parent austenite grain led to a decrease in the fraction of certain boundaries in the martensite and an increase in the connectivity of low energy boundaries, ultimately improving the impact toughness.

Summary: Metastable beta Ti alloys based on the Ti-Nb system have attracted attention due to their unique properties. However, the unstable cyclic behavior of these alloys has hindered their widespread industrial use. Recent studies have shown that internal stresses, including those from dislocations, may be responsible for this behavior. This study demonstrates that inter-cycle thermal treatments can mitigate the unstable cyclic behavior, providing a significant breakthrough in our understanding of Ti-Nb superelastic materials.

Summary: This paper systematically investigated the evolution of microstructure in Fe-Ni-Co-Al polycrystalline alloys and its effects on mechanical properties. The results revealed that the migration of grain boundaries in different processes is driven by different factors, which impacts the grain orientation and precipitate formation. In the process of directional recrystallization, grains with specific orientations grow in the grain boundary region and form the dominant orientation, while grains with lower migration rate form the minor orientation. The alloy produced through directional recrystallization exhibited good recoverable strain and superelastic strain, while the alloy produced through solid solution treatment showed no evident superelastic behavior.

Summary: This study employed laser metal deposition to additively manufacture Ti-15Mo wt% alloy, and subsequently subjected it to post-fabrication uniaxial thermomechanical processing. The results showed that different zones in the microstructure remained after processing, and deformation mechanisms mainly involved slip and martensite formation. The compressive mechanical properties were found to be dependent on strain rate, with higher flow stress and compressive strength observed at higher strain rates. Grain structure homogenisation was not achieved, leading to anisotropic tensile properties.

Summary: This research aims to investigate the effect of roughing and finishing reductions on crystallographic texture. The results show significant heterogeneity in the centerline region, with higher intensity of certain textures. Drop Weight Tear Test indicates that steel specimens with lower and medium reductions exhibit superior low-temperature impact toughness compared to steel with higher reductions. The electrochemical hydrogen charging experiments confirm the presence of internal hydrogen cracks only in steel with lower and medium reductions.

Summary: This study examines the effect of Cr additions on the mechanical behavior of TWIP steel at temperatures ranging from 25°C to 350°C. The results indicate that different temperature-dependent strengthening mechanisms, including mechanical twinning, Dynamic Strain Aging, and slip bands, are at play. The stacking fault energy (SFE) influences the percentage of mechanical twinning, which in turn affects the strain hardening rate.

Summary: This study explores the weldability, microstructures, and mechanical properties of two L1(2)-nanoparticle-strengthened medium-entropy alloys after electron beam welding (EBW). The results show that strong yet ductile defect-free joints were produced, with larger grain sizes in the fusion zones compared to the heat-affected zones and base materials. Both EBWed MEAs exhibited high yield strengths, high ultimate tensile strengths, and good fracture strains at 77 K. The V-doping improved the cryogenic mechanical properties of the TMT MEA.

Summary: The mechanical properties and microstructural evolution of C-doped TRIP-assisted HEA under dynamic loading conditions were systematically investigated in this study. The results showed that dynamic tensile deformation led to an increase in yield strength and a decrease in ultimate tensile strength, with a trend towards increased total elongation. The primary deformation mechanisms shifted from TRIP and TWIP effects to deformation twinning and dislocations. The presence of carbides formed through C-doping hindered dislocation slip and promoted the activation of multiple twinning systems.
