摘    要:以充分均匀化处理的海绵钛和中间合金为原料,研究制备化学成分高均匀性光谱法分析TC11钛合金化学成分用标样的合理工艺,并对影响铸锭合金成分均匀性和冶金质量的主要工艺因素进行分析和探讨。结果表明:采用化学成分合格、粒度适宜的中间合金与海绵钛单块混料均匀制备的自耗电极经真空自耗电弧炉三次熔炼制得的标样冶金质量优异,合金元素及杂质元素分布均匀、波动小,完全满足光谱法分析TC11钛合金化学成分用标样要求。

Abstract: The sponge titanium and master alloys were used as the raw materials. The reasonable technique to prepare the high uniformity TC11 standard sample for spectral analysis was determined. The main process factors affected the uniformity of the chemical property and the metallurgical quality were analysed and discussed. The results show that the TC11 alloy standard sample with good quality, fine uniformity and well satisfied for spectral analysis can be obtained through taking the master alloy of the eligible chemical property and the appropriate size, well-mixed with the sponge titanium as raw materials after three times vacuum arc furnace (VAR) smelting.
