Enhancing the strength-ductility synergy in CoCrNi medium-entropy alloys via grain boundary segregation engineering

The unique solidification behaviour in metal additive manufacturing (AM), can lead to hot cracking, significantly compromising the mechanical properties of the alloys. In this study, grain boundary segregation engineering was employed, using boron (B) as a segregant, to investigate the effects of va...
