摘要	The cracking behaviors of VCoNi medium-entropy alloys with and without short-range order (SRO) structures under different durations of hydrogen charging were investigated. The findings demonstrate that the presence of short-range order in the VCoNi alloy effectively traps hydrogen within the grain interior, thereby mitigating hydrogen segregation at grain boundaries. Consequently, the SRO structure within the VCoNi alloy prolongs the incubation period for hydrogen-induced grain boundary cracking and results in a higher density of grain interior cracks after 12 h of hydrogen charging, indicating that SRO impedes the diffusion of hydrogen into the alloy's interior compared to the alloy lacking SRO. Grain boundary cracking is a consequence of stress concentration and hydrogen segregation at grain boundaries. The initiation of cracks within grains is primarily ascribed to the generation of nanovoids at the intersection of intersecting slip bands.
