Grain Refinement and Mechanical Properties of AZ31 Alloy Processed by Pre-die Forging Extrusion at Different Temperatures
A Mg-3Al-1Zn (AZ31) alloy with highly homogeneous fine grains was fabricated using a simple extrusion method named pre-die forging extrusion (PFE). The strain induced by the pre-forging process resulted in cry...
