Abstract

This study investigates the heat-treatment effect on the microstructure and hardness of the surface oxides of Ti-Zr-Nb alloys. X-ray diffraction results reveal that the Ti-Zr-Nb alloy exhibited a BCC structure. Hardness testing results show that the hardness of the Ti-Zr-Nb alloy gradually increases with the increase of heat-treatment time and approaches 1400 Hv after 60 min heat-treatment at 600 °C. X-ray photoelectron and energy-dispersive X-ray spectroscopy analyses show that the enhancing hardness of the alloys after heat treatment is attributed to the formation of the TiZrNbO4 oxide layer.

Keywords: Ti-Zr-Nb alloy; Heat treatment; Hardness; Microstructure
