本研究的重点是开发具有低杨氏模量的新型钛（Ti）合金，用于可拆卸植入物。本研究以Ti-30 Zr合金为基础合金，研究了Mo对Ti-30 Zr-（0-8 wt.%）合金显微组织、弹性模量和拉伸性能的影响钼）合金进行了研究，在这项研究中，以评估这些合金的生物医学应用的机械相容性。此外，部分设计的合金的细胞相容性进行了检查。实验结果表明，Mo含量对所设计合金的显微组织和力学性能均有显著影响。Ti-30 Zr-（6.7重量%）钼合金，位于（β + ω）/β边界附近，具有亚稳结构，表现出低杨氏模量、高抗拉强度和相当大的伸长率的良好组合。此外，Ti-30 Zr-7 Mo合金具有良好的细胞相容性。(C)2011 Elsevier B.

This research focuses on the development of new titanium (Ti) alloys with a low Young's modulus for use in removable implants. In this study. Ti-30Zr alloy was selected as the base alloy, and the effect of Mo addition on the microstructures, Young's moduli, and tensile properties of Ti-30Zr-(0-8 wt.% Mo) alloys was investigated in this study to assess the mechanical compatibility of these alloys for biomedical applications. Further, the cytocompatibility of a part of the designed alloys was examined. The experimental results indicate that both the microstructures and the mechanical properties of the designed alloys are strongly affected by the Mo contents. The Ti-30Zr-(6, 7 wt.%) Mo alloys, located near the boundary of (beta+omega)/beta with a metastable structure, show a good combination of a low Young's modulus, high tensile strength, fairly large elongation. In addition, Ti-30Zr-7Mo alloy is highly cytocompatible. (C) 2011 Elsevier B.V. All rights reserved.
