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.
Key words: TC11 alloy; standard sample; chemical composition; uniformity
