In this work, cold-rolling was utilized to induce a high density of crystal defects in Al0.3CoCrFeNi high-entropy alloys. The effects annealing temperature on static recrystallization, precipitation behavior and mechanical properties were investigated. With increasing from 590 °C 800 °C, the area fraction recrystallized region increases 26.9% 93.9%. Cold-rolling deformation largely promotes B2 ...

A three-dimensional Monte-Carlo (Potts) model was modified to incorporate the effect of grain-boundary inclination on boundary mobility. For this purpose, a straightforward geometric construction was developed to determine the local orientation of the grain-boundary plane. The combined effects of grain-boundary plane and misorientation on the effective grain-boundary mobility were incorporated ...

The equimolar CoCrFeMnNi alloy is widely studied for its excellent mechanical properties at cryogenic temperatures. Interestingly, it presents a unique combination of strength and ductility mainly due to the occurrence twinning these low Motivated by desire improve room temperature strength, this study focuses on optimization microstructure through alloying thermomechanical treatments. More spe...

The origin of cube recrystallization texture in medium to high stacking-fault energy fcc metals has been debated for almost 70 years. Despite numerous experimental and simulation studies, many issues regarding the nucleation growth grains remain unresolved. Here we apply a full field crystal plasticity model utilizing dislocation density based constitutive theory study deformation evolution cop...

Recent work has indicated that iron (oxyhydr-)oxides are capable of structurally incorporating and releasing metals and nutrients as a result of Fe2+-induced iron oxide recrystallization. In the present paper, we briefly review the current literature examining the mechanisms by which iron oxides recrystallize and summarize how recrystallization affects metal incorporation and release. We also p...
