Title: The effect of deformation processing on tensile ductility of magnesium alloy AZ31
Author: Z. ZUBEROVA, I. SABIROV, Y. ESTRIN
Abstract: A cast magnesium alloy AZ31 was subjected to two different thermo-mechanical process routes, viz. hot cross rolling and hot cross rolling with subsequent equal channel angular pressing. The effect of the deformation processing on the tensile behaviour of the alloy was investigated and interpreted in terms of microstructure and texture effects. In particular, the tensile ductility and its relation to the strain hardening rate and the instantaneous strain rate sensitivity were studied. It was demonstrated that Hart’s necking criterion provides an excellent vehicle for assessment of tensile ductility of the alloy.
Keywords: magnesium alloy, hot cross rolling, equal channel angular pressing, mechanical properties, strain rate sensitivity
