摘要：

Hydrogen induced delayed fracture was investigated in 0.6% O steel with an average ferrite grain size of 0.3 mum and oxide particles of 10 nm. The ultrafine grained steel exhibited markedly high resistance to hydrogen embrittlement at the tensile strength of 1300 MPa by hydrogen trapping effect related to the nanosize oxide particles.
