Abstract

Abstract

Al-Ti-B master alloy is commonly used as grain refining agent to endow aluminum with better organizational properties. In this paper, TiO₂ and B₂O₃ are used as raw materials for the one-step synthesis of Al-Ti-B master alloy by aluminum thermal reduction. The results show that Al-Ti-B master alloy was successfully prepared under the conditions of Al₂O₃∶CaO∶CaF₂=1∶1∶1, roasting temperature 1550 ℃, roasting time 30 min and Al/TiO₂>0.9. The yield of Ti and B is higher than 80%. The Al and B contents of the alloy can be adjusted according to the amount of Al and B₂O₃ in the raw material. The phase of the alloy changes to TiAl and TiB₂ with the increase of the amount of Al and B₂O₃.
