alloys. Therefore, part of Dy and Gd elements in Mg-Dy-Gd-Nd-Zr alloy was replaced by Nd. In addition, Zr was added to the alloy as a grain refining agent. 2 Experimental The master alloy... associated with the instability of secondary precipitates. The fracture mechanism of alloy transfers from intergranular to transgranular with the increase of experimental temperature. Key words: Mg-Dy-Gd......
