    摘要:

    采用粉末冶金方法制備醫(yī)用Ti-Mo合金，通過X射線衍射、掃描電鏡及力學性能測試等方法研究不同工藝參數(shù)對Ti-Mo合金孔隙率、物相、力學性能及斷口形貌的影響規(guī)律。結(jié)果表明：Ti-Mo合金在燒結(jié)溫度為1050 ℃時，可獲得近β型鈦合金。通過調(diào)整壓制壓力、燒結(jié)時間及Mo含量，以調(diào)節(jié)合金的孔隙率、α→β相變等，達到控制Ti-Mo合金的抗彎強度及彈性模量的目的

    Abstract:

    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 °C, the microstructure of Ti-Mo alloys mainly consists of β 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
