Simulation of the Mechanically Induced Self-Propagating Reactions: Theoretical Estimation for MSRs Ignition Time in Zn–S–Sn System

Abstract

The principal parameter of mechanically stimulated self-propagating reactions (MSRs), the induction period of the ignition of combustion, was numerically calculated by taking into account the heat effects of chemical reactions. Accompanying phenomena and MSRs features were studied and discussed. The results were compared with experimental data on the Zn–S–Sn system.

Keywords:

• Combustion ignition time
• Mechanical activation and alloying
• Modeling and calculation
• Reaction kinetics
• Zn–S–Sn system
