Microstructure, Texture and Mechanical Properties of Mg-0.8 Zn-0.3 Gd-0.5 Ca Alloy Sheets

Abstract:

In this study, the microstructure, texture and mechanical properties of rolled Mg-0.8 Zn-0.3 Gd-0.5 Ca sheets have been investigated. It is shown that the as-cast microstructure of the Mg-0.8 Zn-0.3 Gd-0.5 Ca alloy is composed of coarse grains with fine intermetallic particles. The deformed microstructure of the as-rolled sheets results in the non-basal texture with triple peaks. Upon annealing treatment at different temperatures, the fraction of recrystallized microstructure is increased and the grains grow up. With the increase of annealing temperature, the (0002) basal pole of as-rolled sheets has transformed into texture with double peaks firstly and then into triple peaks. Accompanying the change of microstructure and texture, structure and mechanical anisotropy of the rolled sheets is modified.
