Effect of Trace Titanium on Hydrogen Embrittlement Resistance of 25Mn High-Manganese Steel

Taoran Shao, Bingbing Wu, Yanxin Wu, Zhenli Mi

High-manganese steel has emerged as a potential alternative material to austenitic stainless steel for liquid hydrogen storage and transportation environments, owing to its superior mechanical characteristics and limited hydrogen diffusivity. However, its hydrogen embrittlement (HE) susceptibility limits its engineering applications. This study …
