Abstract Scope Driven by the demand for passenger safety and weight reduction in the automotive industry, advanced Fe-Mn-Al-C steels with high specific strength have garnered great attention in recent decades. Unfortunately, these materials are prone to hydrogen embrittlement (HE), which impedes their further application. Understanding HE mechanisms and developing HE mitigation strategies are inevitably important. Here we investigated high-Mn and high-Al lightweight steels with an austenite and ferrite two-phase microstructure and unraveled the underlying mechanism of H-induced failure and the effect of boron on H-induced fracture. We found that HE in this alloy is driven by both H-induced intergranular cracking along austenite-ferrite phase boundaries and H-induced transgranular cracking inside the ferrite. The boron-doped material demonstrates enhanced HE resistance regarding intergranular fracture. Those findings provide new insights into the boundary conditions of different HE mechanisms in high-strength alloys, their interplay and synergistic effects on damage evolution as well as mitigation strategies for HE.
