Abstract
An investigation of mechanically stimulated self-propagating reactions (MSR) has been carried out for different conditions of mechanical activation in the system Zn-Sn-S using a SPEX 8000 mill. Both the earlier obtained and new results are generalized, with focus on the determination of induction period preceding the ignition of exothermal reaction. The discovered features and some hypotheses concerning the mechanism of MSR are discussed.
