Abstract In this paper, Zr-Ti-xNb(x=6, 8, 10, mole fraction, %) alloy is prepared via vacuum non-consumable arc melting furnace. Then the ingot is further processed by forging technology and heat treatment in β single-phase zone. The effect of Nb element on the mechanical properties and corrosion resistance of Zr-Ti based alloys was studied through the measurement of microstructure, mechanical properties and corrosion resistance. Zr-Ti-xNb(x=6, 8, 10) alloys are composed of β phase and α" phase. When the content of Nb element increases, the content of β phase increases, but α" phase content decreases, which indicates Nb improves the stability of β phase. With the increase of Nb content, the yield strength raised from 360 MPa to 780 MPa. The solid solution strengthening effect is obvious. At the same time, stress induced martensitic transformation during the deformation process can greatly improve the tensile strength and plasticity. The increase of Nb content also enhances the corrosion resistance, and the experiments show that those alloys all exhibit strong corrosion resistance in physiological saline.

Key words： Zr-Ti alloy β-phase stability; microstructure mechanical properties corrosion resistance
