that: the dystectic Mg3Sb2 particles formed by Sb and Mg are distributed in the front of dendrite, restrain the growth of the secondary phase and then change the morphology of the secondary phases, which... magnesium alloy consists of the gray matrix and the secondary phases which are semi-continuous strip-like phase in the front of dendrite and blocky phase distributed in the matrix respectively. The as-cast......
