Ball milling induces selfsustaining reactions in many sufficiently exothermic powder mixtures. The process begins with an activation period, during which size reduction, mixing, and defect formation take place. The MSR (mechanically induced selfpropagating reaction) is ignited when the powder reaches a well defined critical state.
