镁合金疲劳与断裂性能的研究进展

his paper summarizes the studies on fatigue and fracture properties of magnesium alloys in recent years. The S-N curves, ε-N curves, the theory of crack initiation and crack propagation, the influence of material factors on fatigue properties of magnesium alloys are analyzed, and the strengthening methods to improve the fatigue properties are also summarized. Mechanical properties and microscopic deformation mechanism of magnesium alloys under high-strain-rate loadings are introduced, and an overview of fracture toughness of magnesium alloys is given.
