Microstructure and Mechanical Properties of Extruded Mg-Zn-Ce-Zr Alloy Rods

Article Preview

Abstract:

Mg-Ce based alloy is a significant extrusion alloy for high ductility and Zn is a promising element for the increase of strength in the alloys. The effects of Zn addition to the Mg-0.5%Ce-0.5%Zr alloy and the extrusion parameters on the microstructures and mechanical properties of Mg-Zn-Ce-Zr alloy have been investigated. The results suggest that Zn element addition will enhance alloy strength and save accepted ductility. The extrusion parameters have been optimized to get the fine grain size, random texture, and therefore to develop a higher ductility and lower yield asymmetry alloy.
