Abstract	A high strain rate multi-directional impact forging (MDIF) was applied to a solutionized Mg-Gd-Y-Zr alloy in the temperature range of 350-500 degrees C. Results demonstrate that the dominant deformation mode is twinning at a temperature below 400 degrees C, whereas at a medium temperature of 450 degrees C considerable continuous dynamic recrystallization was promoted by {10-12} extension twins. At a higher temperature of 500 degrees C, twinning activation was suppressed. New DRX grains were observed but their sizes were much bigger than those resulting from the MDIFed 50 passes at 450 degrees C, which are ascribed to the larger grain boundary mobility and atomic diffusion at 500 degrees C. Moreover, a non-basal weak texture was gained afterward MDIF at each temperature, which is credited to the MDIF process and the minor strain applied in each pass.
