采用X射线衍射仪、光学显微镜、电子万能试验机、维氏硬度计以及纳米压痕仪等研究了Ti85Nb10Sn5合金经不同温度热处理后的显微组织和力学性能。结果表明：773 K热处理后，合金中的α-Ti相和Ti3Sn相的体积分数分别为79.0%和21.0%,而873 K和973 K热处理后，α-Ti相的体积分数分别为95.8%和98.9%,Ti3Sn相的体积分数分别为4.2%和1.1%。经873 K和973 K热处理后，合金具有较大的塑性变形、较高的维氏硬度和较大的弹性能。973 K热处理后，合金的约化弹性模量(Er)为44.0 GPa,与人体骨骼的弹性模量(10～30 GPa)接近，此时合金还具有较大的H/Er和H3/Er~2值，表明合金具有较高的耐磨性和抗磨性。因此，具有较高弹性能和较低约化弹性模量的973 K热处理合金是一种实用价值较高的硬组织植入物材料。
Abstract：Microstructure and mechanical properties of Ti85Nb10Sn5 alloy after heat treatment at different temperatures were investigated by means of X-ray diffractometer, optical microscope, electronic universal testing machine, Vickers hardness tester and nano-indentation instrument. The results show that the volume fractions of α-Ti phase and Ti3Sn phase of the alloy after heat treatment at 773 K are 79.0% and 21.0% respectively, while after heat treatment at 873 K and 973 K, the volume fraction of the α-Ti phase is 95.8% and 98.9%, and the volume fraction of the Ti3Sn phase is 4.2% and 1.1%, respectively. After heat treatment at 873 K and 973 K, the alloy has large plastic deformation, high Vickers hardness and large elastic energy. The reduced elastic modulus(Er) of the alloy after heat treatment at 973 K is 44.0 GPa, which is close to the elastic modulus of human bone(10-30 GPa). At this time, the alloy also has large H/Er and H3/Er~2 values, indicating that the alloy has high wear resistance and anti-wear ability. Therefore, 973 K heat-treated alloy with high elastic energy and low reduced elastic modulus is a kind of hard tissue implant material with high medical value.
