Abstract: With the instant development of third-generation advanced high-strength steels, high strength-ductility automotive steels have been widely adopted. Due to the transformation-induced plasticity effect, medium-manganese steels exhibit significant work-hardening capabilities. However, the hydrogen embrittlement phenomenon caused by its high strength has become a critical issue limiting the industrial application. Therefore, investigating the hydrogen embrittlement susceptibility and resistance mechanisms of medium manganese steels is of great significance. Based on existing research findings, the effects of alloying elements, machining processes, austenite stability and morphology on the hydrogen embrittlement susceptibility of high-strength medium manganese steels were summarized, the strategies for optimizing the resistance to hydrogen embrittlement were proposed, the problems and challenges in research of resisting hydrogen embrittlement were also outlined, and an outlook on future development directions was provided.

Key words: high strength medium manganese steel, hydrogen embrittlement susceptibility, alloying element, machining process, austenite stability
