A precipitation-hardened high-entropy alloy with outstanding tensile properties
Junyang He,Hao Wang,He Huang,Xiandong Xu,Mingwei Chen,Yuan Wu,Xiongjun Liu,T.G. Nieh,Ke An,Zhaoping Lu +9 more
TL;DR: In this paper, the authors demonstrate the possibility to precipitate a coherent reinforcing phase in a fcc-FeCoNiCr HEA matrix using minor additions of Ti and Al, and demonstrate that extraordinary balanced tensile properties at room temperature were achieved, which was due to a well combination of various hardening mechanisms, particularly precipitation hardening.
