| Abstract Scope |
Titanium alloys are widely used in industrial applications due to their excellent properties such as low density, high specific strength, and high corrosion resistance. However, the fabrication and production costs of titanium alloys are high. Powder metallurgy is considered as one promising approach to reduce the production costs of titanium materials. However, the conventional preparation processes of titanium and its alloy powders are generally complicated and high cost. In this study, a novel synthesis method of Ti-Al fine powder was developed using shuttle of disproportionation and proportionation reactions of titanium ions in molten salts. It was found that uniform Ti-Al intermetallic compound powder was produced from titanium and aluminum bulk metals. Furthermore, the composition of produced Ti-Al compound powder, in form of Ti2Al5, TiAl2 and TiAl3, depends on the preparation temperature, but with less dependence in the composition of solvent molten salt. |
