The article describes the aluminothermic reaction in powder systems Nb2O5 (WO3, MoO3, Fe2O3, NiO) - Al after mechanical activation for the production of composite materials based on niobium solid solution reinforced by Al2O3 particles. The study revealed the presence of the necessary and sufficient conditions for the realization of the double stoichiometric …
