Abstract
Herein, an extensive review of the design of titanium alloys with low elastic modulus as implant materials is provided. Due to the high specific strength, low elastic modulus, fatigue resistance, anticorrosion, biocompatibility, and so on, titanium alloys are good biomaterials, especially implant materials. Although lots of titanium alloys are developed for implant materials, the development of new titanium alloys that is toxic‐element free and elastic modulus close/comparable with the bone is still one of the recent and future research focuses. Thus, herein, the effect of elastic modulus on implants, the progress of titanium alloys with low elastic modulus, the toxicity of various alloying elements, and design methods of titanium alloys with low elastic modulus are reviewed. In addition, the development direction of the design method of titanium alloys with a low elastic modulus and the focus of future research are pointed out in the last section.
