Constitutive analysis of wrought Mg-Gd magnesium alloys during hot compression at elevated temperatures

Constitutive behaviors of the newly developed Mg-Gd alloys were studied to make it possible to reveal the effect of Gd addition on the high-temperature deformation behavior of magnesium. It was found that 0.5 wt% Gd is not adequate to increase the flow stress level. In contrast, in the case of 1.5 wt% Gd addition, the level of flow stress increased significantly due to the presence of enough solute Gd atoms. Based on the rigorous constitutive...
