A Comprehensive Review of Modeling Approaches for Analyzing Mechanical Properties and Fatigue Performance in Magnesium Alloys

Abstract

Abstract Magnesium (Mg) alloys have garnered considerable attention across diverse sectors, encompassing aerospace, automotive, and biomedical domains, owing to their advantageous attributes, which include a notably low density (1.7 g/m³), high strength-to-weight ratio, augmented specific stiffness, heightened damping capacity, and exceptional machinability. This paper provides a comprehensive review of the influence of strain amplitude, strain rate, and temperature on the fatigue life of magnesium alloys. The investigation entails a comparative analysis of fatigue life modeling using established models such as Walker’s and Wheeler's models, employing a synthesis of experimental and analytical methodologies. Furthermore, the monotonic mechanical properties, encompassing tensile strength and yield stress, are elucidated across a wide temperature range from room temperature (RT) to 300°C, alongside a comparative evaluation vis-a-vis other material counterpart. The paper also encapsulates a comprehensive review and tabulation of the limited analytical studies pertaining to magnesium alloys available in the literature.
