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 ...

Hierarchical Twin Networks Enable Exceptional Strength and Fracture Toughness in Titanium
A commercial‐purity titanium with hierarchical ultrafine twin structures delivers an exceptional combination of fracture toughness (KJIc) of 187 MPa·m1/2 and specific yield strength of 140 MPa·cm3·g−1, in which pre‐engineered high‐density twin boundaries stimulate massive and

Advancements and Challenges in Liquid Hydrogen Storage Tank Design for Maritime Applications
ABSTRACT In line with the Paris Agreement and the IMO's decarbonization goals, the shipping industry has begun to focus more intensively on adopting alternative fuels to reduce emissions. Among these, hydrogen has attracted considerable attention, with liquid hydrogen (LH2) offering advantages in energy density and storage volume over compressed gas ...

Failure Investigation of Alloy 625 Sockolets After Prolonged Service in an Ammonia Cracker Unit
The failure of the sockolets was caused by intergranular cracking and fracture. The thick and highly brittle nitrided layer formed intergranular surface cracks, which propagated along grain boundaries into the base alloy substrate due to the presence of brittle Cr‐rich carbides. ABSTRACT Several sockolets of Alloy 625 operating at 540°C in contact with

Exploiting Residual Elements Arising from Scrap Steel in Future Sustainable Steel Alloy Design
Herein, the effects of residual elements Cu and Sn on grain growth, recrystallization, and phase transformation in C–Mn steel are summarized, and a case study is presented on how the presence of residual elements can be exploited to reduce deliberate Nb microalloying while achieving the same grain size control and strength during thermomechanical ...
