Equimolar CoCrFeMnNi high-entropy alloy (HEA) could be effectively strengthened by grain
refinement process. However, the dislocations, grain boundaries and twins determined by …

Hydrogen embrittlement is a complex phenomenon resulting in severe deterioration of
ductility or load-bearing capacity of structural metals due to the presence of hydrogen atoms …

High-strength materials usually exhibit low ductility, particularly in the presence of hydrogen
embrittlement phenomena. In this study, three strategies are combined to achieve excellent …

Hydrogen embrittlement behavior, micro-deformation, and crack propagation mechanism of
CoCrFeNiMn high-entropy alloy (HEA) fabricated by laser powder bed fusion (LPBF) under …

High-strength materials usually exhibit poor hydrogen embrittlement resistance, and thus,
there are demands for materials with high strength and good ductility under hydrogen. Here …

The resistance to hydrogen embrittlement (HE) of CrMnFeCoNi high-entropy alloy (HEA) at
