Materials and Processing Designs for High-Performance Magnesium Alloys

Article Preview

Abstract:

Materials and processing designs for advanced magnesium alloys with fine microstructures and superior properties were established by the combination of the repeated plastic working and the Mg2Si synthesis in solid-state. The grain size was less than 1 μm via RPW process due to its severe plastic working on raw powder. The hot extruded magnesium alloys produced in industries showed high ultimate tensile strength, e.g. 420~450MPa, when employing Mg-Zn-Al-Ca-RE (Rare Earth) alloy coarse powder, having 0.5~2 mm diameter, as input materials.
