摘 要：The spheroidizing mechanism of W-phase in the Mg–Zn–Y–Mn–（B） alloys during solid-solution treatment was investigated by using kinetic methodologies. The microstructure and mechanical properties of heat-treated Mg94Zn2.5-Y2.5Mn1 alloy containing 0.003 wt% B were compared with heat-treated Mg94Zn2.5-Y2.5Mn1 alloy. The heat-treated Mg94Zn2.5-Y2.5Mn1 alloy with 0.003 wt% B contained fine and uniform W-phase particles, which exhibited optimal mechanical performance. The ultimate tensile strength, yield strength and elongation were 287.7, 125.5 MPa and 21.1%,respectively.
