The exceptional combination of strength and ductility in multi-component alloys is often
attributed to the interaction of dislocations with the various solute atoms in the alloy. To study …

Shock tolerance is desirable for ceramic particles-reinforced metal matrix composites in
many applications, where the dislocation dynamics evolution under the extreme load is the …

Abstract 3D-DD simulations are performed with cubic grains ranging from 1 to 10 µm to
investigate the physical mechanisms at the origin of the Hall–Petch law. In particular, the …

Modeling dislocation multiplication due to interaction and reactions on a mesoscopic scale
is an important task for the physically meaningful description of stage II hardening in face …

The multiaxial low cycle fatigue behavior of nickel-based alloy 690 at 350° C was
investigated. The multi-slip planar dislocation configuration under non-proportional loading …

Cross-slip of screw dislocations in crystalline solids is a stress-driven thermally activated
process essential to many phenomena during plastic deformation, including dislocation …

Cross-slip is a fundamental process of screw dislocation motion and plays an important role
in the evolution of work hardening and dislocation structuring in metals. Cross-slip has been …

The extreme miniaturization in modern technology calls for deeper insights into the non-
conventional, fluctuation dominated mechanics of materials operating at microscale. For …

A long standing challenge in computational materials science is to establish a quantitative
connection between the macroscopic properties of plastic deformation with the microscopic …

Orientation-dependent irradiation hardening phenomena in pure Zr have been studied, and
the corresponding mechanisms investigated based on the combined use of SEM, TEM, and …
