在生物医学合金中，钛基合金由于其低毒性是目前植入的最佳解决方案。为了提高机械性能，在过去的15年里，人们研究了一些钛合金的一系列化学成分，以提供尽可能接近骨骼的弹性值。本文介绍了Ti-Nb-Ta-Zr合金与其他钛品牌相比的主要力学和显微组织特点。结果表明，在不进行热处理的情况下，Ti15Nb7.6Ta8Zr合金的硬度值最高（437HV1）， Ti98.4合金的硬度值最低（259 HV1）。
Among the biomedical alloys, titanium based alloys are currently the best solution for implantation as a result of their low levels of toxicity. To improve mechanical properties, a series of chemical compositions of some titanium alloys have been studied over the past 15 years, to provide elasticity values as close as possible to bone. The paper presents the main mechanical and microstructural characteristics of Ti-Nb-Ta-Zr alloys compared to other titanium brands. It was found that in the absence of heat treatments, the highest hardness values (437HV1) were obtained for the Ti15Nb7.6Ta8Zr alloy, and the lowest hardness value (259 HV1) was obtained for the Ti98.4 alloy.
