Fatigue and Fracture Characterization of HPDC AM6OB Magnesium Alloy at Cold Temperature

Article

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.
