Research Progress on Hydrogen Embrittlement in Advanced High Strength Steels

The research progress on hydrogen embrittlement in advanced high strength steel (AHSS), especially in dual-phase (DP) steel, transformation-induced plasticity (TRIP) steel, twinning-induced plasticity (TWIP) steel and quenching & partitioning (Q&P) steel, were briefly summarized. The hydrogen embrittlement features, fracture model, fractography and related fracture mechanism of these steels under the hydrogen environment were described in detail so as to provide reference for further research on mechanism of hydrogen embrittlement and relative prevention methods.
