Joint aluminothermic reduction of oxides Zr, Ta and Nb
Butlerov Communications, 2019 Alloys based on the Al-Zr system with insignificant Ta and Nb additives are in demand in the synthesis of complex alloys used to produce titanium alloys for aircraft and rocket technology. A common method for producing aluminum-zirconium alloys and ligatures is the out-of-furnace metallothermal reduction of zirconium from oxides and direct fusion of ...
