英文摘要	The influence of oxygen content on the microstructure and mechanical properties of Ti-23Nb-0.7Ta-2Zr (at%) alloy in as-cast and cold-rolled states was investigated systematically in this paper. It is found that the alloy containing oxygen element is only composed of a single beta phase, while the alloy without oxygen element consisted of beta and alpha aEuro(3) phases. Although the grain size becomes larger, the elastic deformation ratio, strength, and hardness of the alloy are all increased with an increase of oxygen content. The as-cast alloy has excellent plastic deformation ability, but the cold-rolled alloy containing oxygen element exhibits brittle characteristics. A conclusion can be drawn that oxygen element can stabilize beta phase, inhibit the phase transformation from beta to alpha aEuro(3), and furthermore help to increase the strength and elastic deformation ability of the alloy.
