摘要：
We investigated the stretch-flangeability of CoCrFeMnNi high-entropy alloy (HEA) in comparison with other face-centered cubic alloys (304 stainless steel and twinning-induced plasticity steel). The hole expansion ratio of the HEA was superior to those of the other alloys, attributed to fewer vulnerable sites for crack-initiation and the resulting high crack-resistance.
