AZ31 magnesium alloy, direct extrusion, grain size, hardnessAbstract
Direct extrusion of magnesium alloy AZ31 and changes in microstructure resultant from low-speed small-reduction extrusion are presented. The results show possibilities of grain refinement and improvement of mechanical properties associated with limited amount of generated deformation heat in aspect of using as-extruded material as a forging stock.
