To develop new materials of proper elastic modulus and biocompatibility for dental implants, Ti‐2Zr‐xNb‐xSn (x = 0, 0.1, 0.2, 0.3) and Ti‐2Zr‐xNb‐xMo (x = 0, 0.1, 0.2, 0.3) alloys were designed and fabricated. Effects of alloying elements on properties and the feasibility of application in dentistry are analyzed. It is indicated that Nb, Sn and Mo obviously influence the phase compositions of Ti‐2Zr‐based biological alloys. With the increase of alloying element content, all the alloys tend to form a single β‐Ti phase. Ti‐2Zr‐xNb‐xSn alloys exhibit better mechanical properties and corrosion resistance than the Ti‐2Zr‐xNb‐xMo alloys. The Ti‐2Zr‐0.1Nb‐0.1Sn alloy has proper elastic modulus (14.72 GPa) (which is very close to the natural bones), excellent corrosion resistance and comprehensive mechanical properties, and is considered as ideal candidate for implant materials.
