英文摘要In this study, the effect of nitrogen on microstructural evolution and Charpy impact energy of CoCrFeMnNi high-entropy alloy (HEA) was investigated, and the corresponding fracture mechanism was revealed. Nitrogen atoms fully dissolved into the matrix and markedly increased the Charpy impact energy of 0.52 N alloy. The fracture morphologies of the 0 N and 0.52 N alloys were both featured with typical ductile fracture mode, while the serpentine glide morphology of 0.52 N alloy covered wider areas than that of 0 N alloy. Besides, the crack propagation path of 0 N alloy was relatively linear and flat, yet the zigzag crack propagation path was frequently deflected for 0.52 N alloy. The microstructure characterization indicated that the synergistic effect of the increased dislocation density and the more evenly distributed slip system contributed to the enhancement in impact toughness of 0.52 N alloy.
