摘要
研究了以氢化钛粉和Al-V合金粉为原料,采用粉末冶金方法,在真空炉中脱氢烧结一次完成的生产工艺,制备了Ti-6Al-4V合金。其合金性能为:烧结密度4.4g/cm3,抗拉强度854.89MPa,延伸率3.8%,达到国外相同水平。该方法简化了钛粉制备工艺,有利于降低最终产品杂质含量和节能。
Powder metallurgy of the Ti-6Al-4V alloy using titanium hydride powder and Al-V alloy powder, in vacuum furnace where dehydrogenizing and sintering could be joined has been researched.The results show that sintering density 4.4 g/m^3, tensile strength 854.89 MPa and elongation 3.8%.Above mentioned,these properties are in step with abroad,and that the technique of Ti powder produced was simplified, as a result decreased the inclusion in the alloy and reduced energy cost.
