摘　　要：采用粉末冶金方法制备医用Ti-Mo合金,通过X射线衍射、扫描电镜及力学性能测试等方法研究不同工艺参数对Ti-Mo合金孔隙率、物相、力学性能及断口形貌的影响规律。结果表明:Ti-Mo合金在烧结温度为1050℃时,可获得近β型钛合金。通过调整压制压力、烧结时间及Mo含量,以调节合金的孔隙率、α→β相变等,达到控制Ti-Mo合金的抗弯强度及弹性模量的目的。The medical Ti-Mo alloys were fabricated by powder metallurgy. The effects of different process parameters on the phase, the morphology and the mechanical properties of Ti-Mo alloys were investigated through X-ray diffraction （XRD）, scanning electron microscopy （SEM） and mechanical properties test methods. The results show that after sintering at 1050 ℃, the microstructure of Ti-Mo alloys mainly consists offl phase. By adjusting the pressure, sintering time and Mo contents to regulate the porosity of Ti-Mo alloy and α→β phase transition, thus the flexural strength and the elastic modulus of Ti-Mo alloys can be controlled.
