Abstract Scope The phase stability of B2 phase in the ZrTiHfCuNiFe HEA was investigated in comparison with that of the amorphous phase of the same composition. Annealed at 750-850 C, the HEA casting rod and amorphous ribbon exhibit the same predominant B2 phase. While annealed at 600 C and below even for prolonged annealing time 1000 h, no phase transformation is observed in the HEA casting rod with B2 phase, whereas multiple phases (i.e. (Cu,Ni)10(Zr,Hf)7, ordered HCP, B2 and FeTi) are formed in the amorphous ribbon. The B2 phase obtained by annealing amorphous ribbon at high temperature does remain its B2 structure when annealed at 600 C again. These observations clearly indicate that B2 phase in the ZrTiHfCuNiFe HEA exhibits higher thermal stability at 600 C and below compared with the amorphous phase of the same composition, which may be attributed to the low phase transformation temperature and coordinated long-range sluggish diffusion.
