Experimental Evaluation of the Interaction of Titanium and Gadolinium Oxides with Aluminum
- 9 Downloads
The sequence of formation of compounds in the Al–TiO2–Gd2O3 system is determined using theoretical and experimental evaluations of the aluminothermic reduction of titanium and gadolinium from oxides. The reduction has two stages and proceeds via the stage of titanium monoxide formation followed by the formation of the Al3Ti and GdAl2 intermetallic compounds.
Keywords:titanium alloy aluminothermic reduction phase formation gadolinium intermetallic compounds
The experimental studies were carried out on the equipment of the Center for Collective Use URAL-M, Institute of Metallurgy, Ural Branch, Russian Academy of Sciences.
