β型钛合金的低杨氏模量使其有利于用于医疗植入器械，因为它们在防止骨吸收和促进良好的骨重建方面都是有效的。本文描述了用于生物医学应用的低杨氏模量β型钛合金的开发，沿着讨论了用于更大模量降低的合适方法。由于经常需要取出植入器械，因此还描述了适用于可取出植入物的钛合金。最近注意到，尽管患者需要低杨氏模量的钛合金，但外科医生需要高模量。因此，β型钛合金的杨氏模量自调也进行了探索。根据动物试验结果，对低杨氏模量β型钛合金在防止应力遮挡方面的有效性进行了评价。还描述了用于生物医学应用的增强β-型钛合金的机械生物相容性的方法，以及沿着那些表现出超弹性和形状记忆行为的β-型钛合金的适用性。最后，讨论了一些β型钛合金在生物医学应用中的独特行为。
The low Young's modulus of beta-type titanium alloys makes them advantageous for use in medical implant devices, as they are effective in both preventing bone resorption and promoting good bone remodeling. The development of low Young's modulus beta-type titanium alloys for biomedical applications is described herein, along with a discussion of suitable methods for even greater modulus reductions. Since there is often occasion to remove implant devices, titanium alloys suitable for removable implants are also described. It has recently been noted that although patients require low Young's modulus titanium alloys, a high modulus is needed by surgeons. Consequently, beta-type titanium alloys with a self-tunable Young's modulus are also explored. An evaluation of the effectiveness of low Young's modulus beta-type titanium alloys in preventing stress shielding is provided, which is based on the results of animal testing. Means of enhancing the mechanical biocompatibilities of beta-type titanium alloys for biomedical applications are also described along with the suitability of those beta-type titanium alloys which exhibit super-elastic and shape-memory behavior. Finally, the unique behavior of some beta-type titanium alloys for biomedical applications is discussed.
