Abstract This study investigated the effect of oxygen doping on the crystalline structure, microstructure, and selected mechanical properties (Vickers microhardness, Young's modulus and internal friction) of Ti-15Zr-xMo (x = 5, 7.5, 10, 15 and 20 wt%) alloys for use as biomaterials. The monitoring of oxygen pressure along with the doping treatment indicated that the interstitial element was successfully absorbed into the samples. Results showed that oxygen content slightly altered the α”/β phase proportion and β phase crystalline parameter without abruptly changing their microstructure. Moreover, the selected mechanical properties suffered variations in a non-linear manner. Oxygen content was found to be suitable to produce small variations in the microstructure and in the selected properties of biomedical Ti alloys, keeping the main composition unchanged.

通过氧掺杂调整生物医用 Ti-15Zr-Mo 合金的微观结构和选定的机械性能

摘要 本研究调查了氧掺杂对 Ti-15Zr-xMo (x = 5、7.5、10、15 和 20 wt%) 的晶体结构、微观结构和选定机械性能（维氏显微硬度、杨氏模量和内摩擦）的影响。 ) 用作生物材料的合金。氧压监测和掺杂处理表明间隙元素被成功吸收到样品中。结果表明，氧含量略微改变了 α”/β 相比例和 β 相结晶参数，而不会突然改变其微观结构。此外，选定的机械性能以非线性方式发生变化。发现氧含量适合在生物医学钛合金的微观结构和选定的特性中产生小的变化，
