Fracture-based modeling of heat-treated AZ91/AZE911 magnesium alloys for estimating high-cycle fatigue lifetime by Paris crack growth rate and striations spacing

Abstract: In the present research, the fracture behavior of the AZ91 magnesium alloy is analyzed based on the striations spacing on the fracture surface for predicting the fatigue High-Cycle Fatigue lifetime. At first, equations and relations were extracted based on the Paris law. Then, striations spacing was measured using ImageJ software and field emission scanning electron microscope images of fracture surfaces of heat-treated Mg–Al–Zn alloys, containing and non-containing 1% rare earth elements (1% RE). Finally, con… Show more
