摘　　要：本文通过选择合适中间合金,并控制最佳熔炼工艺,以真空自耗电弧三次熔炼制备了名义成分为Ti-6Al-4VELI-0.10Ru(质量分数)的含钌钛合金Gr29铸锭。结果表明:该工艺能够准确得到预期的化学成分,其主元素Al、V在铸锭横截面的径向上分布均匀,微量的高熔点Ru元素在铸锭纵截面中心轴线上的质量分数与目标成分偏差为±0.01%,并且均匀分布于铸锭上中下位置,显示出优良的冶金质量。Using optimizedmaster alloys and controlling the smelting process,the Ti-6Al-4VELI-0.10Ru(mass fraction)alloy ingot was prepared by means of Vacuum Arc Remelting(VAR)process.The results show that the expected chemical composition is obtained,and the ingot exhibits homogeneous element distribution,especially the aluminum,vanadium element,in its transverse section.Deviation of high melting point ruthenium content along the middle axis of ingot longitudinal section is about±0.01%.
