Enhanced plasticity mediated by disclination-assisted accommodation and twinning-induced work hardening in an elliptical-textured Mg alloy

Journal of Magnesium and Alloys
Crystallographic texture engineering is a key strategy for enhancing the mechanical properties of polycrystalline magnesium (Mg) alloys. Due to the intrinsic anisotropy of the hexagonal close-packed (HCP) structure, the deformation behavior of Mg alloys ...

Elastic Deformation of Polycrystals

, 2002
We propose a framework to model elastic properties of polycrystals by coupling crystal orientational degrees of freedom with elastic strains. Our model encodes crystal symmetries and takes into account explicitly the strain compatibility induced long ...
