It has long been known that iron undergoes a phase transformation from body-centered
cubic/α structure to the metastable hexagonal close-packed/ε phase under high pressure …

Plastic deformation of crystalline materials at low temperatures occurs by dislocation
movements; hence, the resistance to dislocation motion controls material strength. For …

The material strengths of polycrystalline metals have been widely predicted according to the
grain size, where yield stress is governed by slip transfer through the grain boundary (GB) …

The effect of the dislocation density on yield strength and subsequent plastic deformation of
ultrafine-grained metals was investigated in large-scale atomistic simulations …

A nanocrystalline metal contains grains that are extremely small, with a high proportion of
grain boundary (GB). For understanding of the mechanical properties of nanocrystalline …

The effects of interface strength and stacking fault energy on the slip transmission of a
dissociated dislocation across a coherent interface are investigated using phase field …
