Abstract: Microstructure and texture evolution of Mg-8Gd-4Y-Nd-Zr alloy during hot compression were in-vestigated using optical microscopy (OM), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and texture testing. The results indicated that the basal texture was formed after deformation. However, both the basal slip and prismatic slip systems were activated due to the high deformation temperature, and the basal texture was coexisted with the prismatic texture. Then, twinning occurred in the grains with prismatic orientation, and the basal plane of the twin-ning zone was approximately parallel to the compression plane. The dynamic recrystallization was then occurred at the twin boundaries, which also resulted in the formation of basal texture.
