Microstructures and properties of rolled Mg-9Gd-4Y-0.6Mn(nominal wt%)sheets solution treated at 793K for 12h, and aged at various combinations of temperatures and time were investigated by hardness measurement, tensile test and TEM. The evolution of the precipitates and their effect on the mechanical properties of the pre-, peak-, and over-aged tempers were determined, and the optimal yield tensile strength (YTS) and ultimate tensile strength (UTS) were 276MPa and 287MPa at room temperature, respectively. It has been found that the addition of Mn into Mg-Gd-Y system contributes to block behavior of matrix diffuse and increase potential of heat resistance of the alloy.
