Abstract
The mathematical model of thermal explosion and synthesis of products in a mechanically activated 3Ni + Al mixture is simulated in a macroscopic approximation. It is shown that activation of original components significantly increases the formation rate of a Ni3Al intermetallide. The experimental data are used to determine the thermophysical and kinetic constants of the process.
