通过粉末冶金元素混合法,制备含α及β相的Ti-Al-Mo-V-Ag合金。通过X射线衍射、金相观察、扫描电镜观察及力学性能测试,研究Ag的添加及烧结温度对Ti-5Al-4Mo-4V合金的组织与性能影响。结果表明:Ag的添加能提高粉末冶金Ti-5Al-4Mo-4V合金的的相对密度,改善合金的力学性能;在1250℃下烧结4h后,Ti-5Al-4Mo-4V-5Ag合金的相对密度及抗压缩强度分别达到96.3%和1656MPa。 The Ti-Al-Mo-V-Ag alloy containing α and β phases was prepared by the powder metallurgy element mixing method. The effects of Ag addition and sintering temperature on the microstructure and properties of Ti-5Al-4Mo-4V alloy were investigated by X-ray diffraction, metallographic observation, scanning electron microscopy and mechanical properties tests. The results show that the relative density of Ti-5Al-4Mo-4V alloy increases with the addition of Ag, and the mechanical properties of Ti-5Al-4Mo-4V alloy are improved. After sintering at 1250 ℃ for 4h, the relative density And compressive strength reached 96.3% and 1656MPa respectively.
