Abstract

In this study, the role of texture on the quasi-static and dynamic response of pure magnesium and magnesium alloy AZ31B is investigated. Texture is imparted through thermo-mechanical processes of hot-rolling or equal channel angular extrusion. Constant strain-rate, both dynamic and quasi-static, and strain-rate jump experiments, dynamic-quasi-static, quasi-static-dynamic and dynamic-dynamic, are used to examine plastic flow anisotropy and strain hardening response. Observations of the macroscopic material behavior, specifically the stress-trajectory, are supported by electron back-scatter diffraction analysis to gain insights of texture evolution and predominant deformation processes taking place during deformation increments.
