Abstract:The influence of Gd concentration on texture and stretch formability of rolled Mg-Zn-Gd alloys were investigated. The result shows that Gd addition in Mg-Zn alloys can effectively modify the basal plane texture. The alloy with 0.2% Gd concentration appears to be low texture intensity, TD-split texture occurs when the position of basal is titled from ND toward TD, and the largest Erichsen value is 6.5 while the elongation rate reaches 29.1% in TD direction. However with Gd concentration increasing, when the Gd concentration is 2.0%, the texture intensity increases slightly, TD-split texture degree decreases dramatically, and Erichsen value is only 3.9. Excessive Gd addition promotes formation of the coarse second phase particles, resulting in the deterioration of stretch formability
