Abstract

An investigation of the fatigue and fracture characterization of the high pressure die cast (HPDC) AM60B magnesium alloy at −40 °C temperature was conducted by means of the constant load amplitude fatigue test. The results demonstrated that low temperature had a significant influence on alloy’s fatigue life; the life increased at −40 °C temperature as compared to that at room temperature. The fracture surfaces of the tested specimens were observed under a scanning electron microscope (SEM) to further understand the fracture phenomenon at low temperature.
