Paper Title:
Effects of Differential Speed Rolling on Microstructure and Mechanical Properties of AZ31 Magnesium Alloy
  Abstract

A differential speed rolling (DSR) processing with a roll speed ratio of 1.167 was carried out on an AZ31 alloy for investigating the effects of DSR on microstructure, texture and mechanical properties. The DSR processed sheet showed unidirectional shear bands with a small grain size of 5.5 μm inclining to the rolling direction, and the basal plane tended to incline at about 15º from the rolling plane toward the rolling direction. Compared with the normal rolled sheet, the DSR processed sheets showed a lower proof stress and a larger elongation with an increase from 21% to 26% in the rolling direction. The proof stress increased and the elongation decreased with the angle between the tensile direction and the rolling direction.
