Abstract

The Charpy impact results for Mg-10Gd-3Y-0.5Zr and Mg-11Y-5Gd-2Zn-0.5Zr alloys at various temperatures showed that Mg-10Gd-3Y-0.5Zr was more sensitive to temperature. The increase in impact toughness with temperature was related to the blunt crack-tip at high temperatures. The delamination and local melt of matrix were responsible for the brittle-to-ductile transition of GW103 alloy. The branch and bridging of cracks resulting from ordered phases played an import role in the change in fracture mode from cleavage fracture to quasi-cleavage and dimple-fracture for WGZ1152 alloy.
