钛及其合金广泛应用于生物医学领域。早期的工作更关注利用其优异的耐腐蚀性和生物相容性。然而，现在的趋势是更多地利用它们良好的力量/重量特性。在压力下操作钛合金，特别是在本质上是循环的情况下，会引入其他设计问题，而其他领域（例如航空航天工业）的研究已经在解决这些问题。这些问题包括微观结构和织构的作用、缺陷容限和应力腐蚀敏感性。本文对这些主题进行了简要介绍，以期影响未来的种植体设计，以避免灾难性的使用故障。
Titanium and its alloys are used widely in biomedical applications. Early work was more concerned with utilising their excellent corrosion resistance and biocompatibility. Now, however, the trend is to make more use of their good strength/weight characteristics. Operating titanium alloys under stress, particularly if it is cyclic in nature, introduces other problems of design that research in other fields, such as the aerospace industry, is already addressing. Such problems include the role of microstructure and texture, defect tolerance and stress corrosion susceptibility. The present paper provides a brief introduction to these topics with a view to influencing future implant design so as to avoid catastrophic inservice failures.
