Abstract

The results of testing method of synthesis of a high-entropy AlNbTiVZr alloy using metallothermic reduction of group IV and V metals from their oxides are presented. At the first stage, joint aluminothermic reduction of metals was performed in a resistance furnace. Then, to achieve uniformity and remove harmful impurities, the metal was remelted in a vacuum furnace with an inert atmosphere. The alloy obtained after the second remelting was subjected to chemical and x-ray phase analysis. The results of the analysis revealed the presence of a solid solution of Zr (Nb, V) with TiAl inclusions, confirming the prospect of using metallothermic synthesis to produce a high-entropy alloy with a single-phase structure.
