Texture and anisotropy in magnesium alloys

Abstract

The characteristics and components of textures in magnesium alloys were presented. The mechanism of the formation and evolution of textures during plastic deformation such as extrusion, rolling, equal channel angle extrusion processes and annealing were reviewed, followed by the analysis of the effects of textures on mechanical properties of magnesium alloys. The influences of main factors such as alloy elements, deformation temperature, strain, strain rate and grain size on texture and anisotropy of magnesium alloys were discussed. The results show that textures affect mechanical properties of magnesium alloys mainly by altering the Schmid factors of all slips, especially basal slip systems and inducing texture strengthening and softening.
