(abstract)

In this study, the effect of hydrogen on the evolution of the deformation microstructure in 2Mn-0.1C steel mainly composed of ferrite microstructure was systematically investigated. We found that the densities of the total dislocations (existing outside the LEDS boundaries and constituting LEDS boundaries) were higher in the hydrogen-charged specimens. In addition, we conclude that hydrogen increases the relative mobility of screw dislocations to edge dislocation, leading to the frequent cutting of screw dislocations and tangled dislocation morphology.
