Metals that come into contact with the body can cause reactions in the body, so biomaterials must be tested to avoid side effects. Mo, Zr, and Ta are non-toxic elements; alloyed with titanium, they have very good biocompatibility properties and mechanical properties. The paper aims to study an original Ti20Mo7ZrTa system (5, 10, 15 wt %) from a mechanical and in vitro biocompatibility point of view. Alloys were examined by optical microstructure, tensile strength, fractographic analysis, and in vitro assay. The obtained results indicate very good mechanical and biological properties, recommending them for future orthopedic medical applications.

与身体接触的金属会在体内引发反应，因此生物材料必须经过测试以避免副作用。钼、锆和钽是无毒元素；与钛合金化后，它们具有非常好的生物相容性和机械性能。本文旨在从力学和体外生物相容性的角度研究一种原始的Ti20Mo7ZrTa体系（5%、10%、15%重量百分比）。通过光学微观结构、拉伸强度、断口分析和体外试验对合金进行了检测。所得结果表明其具有非常好的力学和生物学性能，推荐将其用于未来的骨科医学应用。
