Mechanical Activation and Thermal Treatment of Low-Energy Nb-2Si Powder Blend. The Experiment. II. Mathematical Model

Аннотация

The paper proposes a mathematical model of thermal explosion in mechanically activated Nb–2Si powder blend. A study of the dynamics of mechanical activation synthesis of the Nb–Si system shows that preliminary activation of the initial powder components intensifies the formation of NbSi₂ phase. Thermokinetic and thermophysical constants are obtained for the mechanochemical synthesis using the experimental data and the inverse problem method.
