In order to develop new β-type Ti-based biochemical materials, a series of Ti-10Mo-1.25Si-xZr (x=4-13) alloys were designed and prepared using vacuum arc melting method. Phase analysis and microstructural observation showed that all the as cast samples consisted of equiaxed β-Ti phase. With the increase of Zr content, the structure of grain boundary changed from semi-continuous network to denser granular, and the microstructure was refined. The solid solution effect of the β-phase stabilization elements (i.e. Mo, Zr and Si) predominantly determined the mechanical properties. These β-type Ti-10Mo-1.25Si-xZr biomaterials exhibited a good combination of high compressive strength, high yield stress, good plasticity, as well as rather low Young's modulus (in the range of 23.086 GPa-32.623 GPa), which may offer potential advantages in the applications in hard tissue replacements (HTRs).
为了开发新型β型钛基生物化学材料，采用真空电弧熔炼法设计并制备了一系列 Ti-10Mo-1.25Si-xZr（x=4-13）合金。相分析和微观结构观察表明，所有铸态样品均由等轴β-Ti 相组成。随着 Zr 含量的增加，晶界结构由半连续网络状变为更致密的颗粒状，微观结构得到细化。β 相稳定元素（即 Mo、Zr 和 Si）的固溶效应主要决定了材料的力学性能。这些β型 Ti-10Mo-1.25Si-xZr 生物材料表现出高抗压强度、高屈服应力、良好的塑性以及相当低的杨氏模量（23.086-32.623 GPa）的良好组合，这可能为在硬组织替代物（HTRs）中的应用提供潜在优势。
