〈div〉〈p〉The Ti-13Nb-13Zr-10Cu alloy as new biomedical material was prepared by Ar-arc melting. The microstructure characteristics, mechanical properties and antibacterial properties of Ti-13Nb-13Zr-10Cu alloy after heat treatment were studied. Results show that the Ti-13Nb-13Zr-10Cu alloy is mainly composed of 〈em〉β〈/em〉-Ti, 〈em〉α〈/em〉-Ti, and some Cu-containing phases, 〈em〉e.g.〈/em〉 CuZr, Ti〈sub〉2〈/sub〉Cu, and Cu〈sub〉10〈/sub〉Zr〈sub〉7〈/sub〉. With the addition of Cu, the 〈em〉α〈/em〉-Ti phase significantly decreased, and some Cu-containing phases appeared in the form of reticular structure, which was mainly consisted of Cu, Zr and Ti elements. The CuZr and Ti〈sub〉2〈/sub〉Cu phases in the reticular structure were identified by TEM. Compared with CP-Ti and Ti-13Nb-13Zr alloy, the elastic modulus of Ti-13Nb-13Zr-10Cu alloy was significantly reduced to 66 GPa, but its yield strength and compressive strength still retained at high levels. The Ti-13Nb-13Zr-10Cu alloy after 24 h of culture with 〈em〉S. aureus〈/em〉 exhibits an enhanced antibacterial activity.〈/p〉〈/div〉
