Isothermal fatigue tests were carred out on Mg-12Gd-3Y-0.5Zr magnesium alloy and its heat-treated counterpart at different temperatures. The exprimental results shows that isothermal fatigue strength of two alloys decrease very slowly with increasing temperature up to 200°C. The ultimate tensile strength of heattreated Mg-12Gd-3Y-0.5Zr is slight lower than that of as-rolled counterpart, however, the fatigue strength of heat-treated alloy is higher.
