Summary

The effect of test temperature ranging from -25 to +50 °C on mechanical properties of the high-strength wrought magnesium alloy AZ80 was evaluated. While yield stress and tensile strength within this temperature range continuously increased with decreasing temperature, the 107 cycles notch fatigue strength in fully reversed loading exhibited a marked minimum at T = 0 °C. Shot peening was found to improve the fatigue strength at all tested temperatures.
