Abstract
The present study reasonably designed and prepared a novel Zr22.5Ti22.5Hf22.5Ni22.5Ta10 high-entropy amorphous alloy with excellent thermal stability and corrosion resistance. The hysteresis diffusion effect caused by the high mixing entropy of the multi-principal system affects the formation of the crystalline phase and thus improves thermal stability. The alloy exhibits excellent corrosion resistance compared to 316 L in 3.5 wt% NaCl solution. The XPS results indicate that the passive film of Zr22.5Ti22.5Hf22.5Ni22.5Ta10 passive film is rich in oxides of Zr, Ti, Hf, and Ta, which has excellent resistance to chloride ion attack.
