A method combining molecular dynamics (MD) and Monte Carlo (MC) simulation is used to analyze the short-range ordering and grain boundary (GB) segregation in the bi-crystals of equiatomic CoCrFeNi and Al (8 at%)-CoCrFeNi high-entropy alloys (HEAs). Based on the structures of the two HEAs obtained by...
