Cu-Fe-Ti-Zr high entropy alloys (HEAs) systems could give enormous attention with extreme mechanical and corrosion resistance porperties. In this research, Cu-Fe-Ti-Zr-Nix alloys were prepared by arc melting and annealing at 900°C to investigate the effect of Ni content on microstructure, hardness, and corrosion resistance behavior. As the Ni content is increased, the microstructure was changed from B2_BCC and Laves_C14 to FCC and B2_BCC at Ni0.1 and Ni0.3, Laves_C14 at Ni0.5, and FCC, B2_BCC, Cu51Zr14, and Laves_C14 at Ni0.8 and Ni1.0. The intermetallic compounds (IMCs) which were caused by the refractory elements (Ti and Zr) and atomic size difference were found in dendritic microstructure in the Cu-Fe-Ti-Zr-Nix alloys. The hardness and corrosion behavior of the Cu-Fe-Ti-Zr-Nix alloys were revealed that when Ni content was increased, the hardness of the Cu-Fe-Ti-Zr-Nix alloys was gradually decreased, and better corrosion resistance in NaCl solution was observed.
