Understanding the hydrogen effect on pop-in behavior of an equiatomic high-entropy alloy during in-situ nanoindentation
文献摘要：
Hydrogen embrittlement has been recognized as a serious prob-lem in the application of metallic structural materials,where hy-drogen degrades the mechanical properties of the material,lead-ing to an unpredictable failure[1-6].Despite intense studies,the fundamental mechanism of hydrogen embrittlement is still inade-quately understood.Recently,it has been widely observed and ac-cepted that the interaction between hydrogen and dislocations is a key factor for causing the embrittlement phenomenon[7-12].The hydrogen effect on dislocation behavior has been studied by in-situ transmission electron microscopy(TEM),which shows that hydro-gen facilitates dislocation motion and promotes planar slip owing to its shielding effect at local stress field[13].However,the elec-tron beam produces local heating and high hydrogen fugacity on the thin foil,making this observation difficult to interpret.On the other hand,atomistic simulation has been performed to investi-gate the hydrogen effect on dislocation mobility,and in contrast,the outcome indicates a resistance to edge dislocation motion by dissolved hydrogen without shielding effect[14].
