Abstract
The present work aims to evaluate different techniques formability of magnesium alloys. The material was selected for an axisymmetric extrusion tests, namely AZ31. After normal hot extrusion, the plasticity of magnesium alloy will be improved, but not noticeably. In this paper, further extrusion with different deformation is adopted to commercial AZ31 magnesium alloy rods at different temperatures in order to research the effects on grain size and properties of the different extrusion techniques. Through a mass of experiments, it is proven that hot deformation can refine the grain size effectively, but limited.
