摘要：
The microstructure and corrosion properties of Ti-Zr-Nb high entropy alloys (HEAs) were studied. The results show that the microstructure of the Ti-Zr-Nb alloy was composed of a single BCC phase. Addition of V in Ti-Zr-Nb alloys has little effect on the microstructure of the alloys, but additon of Al will induce ordered B2 phase structure. During the corrosion process in 360 ℃ water and in high temperature steam, the corrosion oxide layer on TiZrNb alloy will spall. Appropriate amount of Al addition (atomic percentage about 15%), will increase the stability of oxide layer formed on Ti-Zr-Nb alloys in 360℃ water and in high temperature steam, and will inhibit the spallation of oxide layer. Large amount of Al addition (atomic percentage is about 25%), corrosion acceleration will happen during the corrosion of alloys in 360℃ water. Certain amount of Al addition will increase the corrosion property of Ti-Zr-Nb alloys, while large content of Al will decrease the corrosion property. © 2021, Editorial Board of Atomic Energy Science and Technology.
