| Abstract: |
| The feasibility to produce Ti-Al-xFe-ySi mutielement alloy from titanium slag by aluminothermic reduction was theoretically analyzed. Possible chemical reactions between metallic oxide in titanium slag and aluminum were calculated and analyzed. The priority reduction degree of metallic oxide was discussed. The results show that it is feasible to produce Ti-Al-xFe-ySi mutielement alloy from titanium slag by aluminothermic reduction. Main binary alloy phase presents as Ti5Si3, TiAl3, and TiFe from thermodynamics analysis and validated by experiments. Main phases of prepared alloy include Al2.68Mn0.32Ti and Al3Ti0.75Fe0.25, and a small amount of TiFe and Ti3SiC2. |
