In the absence and presence of hydrogen, the change of dislocation structure as increasing strain in a coarse-grained polycrystalline Cu was compared. By classifying dislocation structure with crystallographic orientation, it was found that hydrogen has almost no effect on the tensile property and dislocation evolution in coarse-grained Cu. Density functional calculation was used to reveal the underlying dislocation-H interaction mechanism in Cu. The electron structure interaction between Cu and H was the main factor that inhibited the hydrogen accumulation around dislocation, and it was attributed as the principal reason for high resistance to hydrogen embrittlement of coarse-grained Cu.
