Abstract

Microstructural formation mechanism of NiCoFeCuMn equiatomic high-entropy alloys has been discussed from a viewpoint of interaction energy. It is indicated that when the interaction energy (Iij) is higher than a threshold value (It), spinodal decomposition may occur, leading to segregation of similar atoms and formation of a phase independently. Segregation of similar atoms is prone to appear in the alloys containing Fe–Cu or Cu–Cr components. However, when it is Iij < It, heterogeneous atoms segregation may appear. Components like Mn–Ni, Mn–Cu and Mn–Co et al. in the NiCoFeCuMn alloy prone to segregate. For the equiatomic HEAs, interaction energy Iij can effectively reflect the formation mechanism of single-FCC crystal structure and is a principle criterion for material design.
