Abstract

In this paper, the hydrogen induced cracking behavior of the Co₃₀Cr₁₀Fe₁₀Al₁₈Ni₃₀Mo₂ eutectic high entropy alloy was studied. The results showed that the strength and ductility of the alloy decreased after hydrogen pre-charging, and quasi-cleavage fracture features and hydrogen-induced cracks were found. Moreover, the cracks induced by hydrogen pre-charging were found to propagate along the two-phase interface and inside the BCC phase.
