- Abstract
- Deoxidation of beta-titanium was investigated by Ca-CaCl2 and Ca-CaF2 fluxes at 900 to 1400 degrees C. The content of oxygen in Ti was strongly dependent not only on the Ca potential but on the stability of CaO in the fluxes. The present experimental results indicate that deoxidation of Ti by Ca-calcium halide fluxes could be controlled by the activity ratio of CaO to Ca. The ratio of a(CaO)/a(Ca) = 0.06 similar to 0.1 was strongly recommended for obtaining oxygen content of 40 similar to 160ppm. [doi:10.2320/matertrans.MRP2008284]
