Review on fatigue performance of Fe-Mn-Al-C low density steels
During the implementation of the"Dual Carbon"strategy,automotive lightweight has turned into a significant trend in the development of the automotive industry.As one of lightweight materials,Fe-Mn-Al-C low density steels,have attracted extensive attention owing to a combination of low density,high strength-plasticity balance and good toughness.Another critical consideration for lightweight materials used in automotive body structure and components is their safety performance.Hence,the service performance of Fe-Mn-Al-C low density steels is the key issue in achieving the application.The composition design and tensile properties of Fe-Mn-Al-C low density steels were briefly introduced,and the research progress on the fatigue performance corresponding to the factors of alloy elements,grain size,and secondary phases was focused on.
