Strengthened microstructure and mechanical properties of austenitic 316L stainless steels by grain refinement and solute segregation

Journal of Materials Research and Technology
Strengthening conventional materials through additive manufacturing is generally understood to occur due to rapid cooling in the metallurgical process, which refines the microstructure by producing smaller grain sizes and segregating elements at specific

Structurally Complex Precipitates Enhance Strength‐Ductility Synergy in a Duplex Medium Entropy Alloy

Advanced Science, EarlyView.
Strong‐yet‐ductile precipitation‐hardening alloys require novel microstructural complexity of precipitates in particularly at cryogenic condition, to constantly impart strain hardening of hard‐and‐brittle precipitates. The present work creates innovative structurally complex precipitates assembled with dispersed nanocores and a chemical‐heterogeneity ...

Development and Applications of a Magnetism‐Aware General‐Purpose Atomic Cluster Expansion Potential for the Fe‐O‐H Ternary System

Advanced Science, EarlyView.
Hydrogen‐driven iron oxide reduction, water‐iron corrosion, and hydrogen embrittlement of metallic iron share the same Fe‐O‐H chemistry. A general‐purpose Atomic Cluster Expansion potential covers this chemistry across the full concentration range with explicit Ising‐like treatment of magnetism.

Effect of Oxygen and Nitrogen Oxide Gas Concentration on Corrosion of 310N Stainless Steel in Solar Salt at 600°C

Materials and Corrosion, EarlyView.
Schematic depicting corrosion layer formation and changes in stainless steel exposed to Solar Salt at 600°C for 1000 h under different atmospheres: (a) N2 accelerates salt decomposition, producing nitrite and oxide ions, causing severe corrosion. (b) Adding O2 reduces nitrite ions formation, resulting in less corrosion than N2 alone.
