Abstract

An incubation time exists for the formation of MoSi2 by mechanical alloying (MA). For the particular milling conditions employed, the bulk of MoSi2 formation occurs between 3 h and 12 min and 3 h and 13 min. This abrupt formation of MoSi2 during MA suggests that the reaction occurs by a form of self-propagating high-temperature synthesis (SHS), when a critical amount of stored energy (in the form of interfacial energy and cold work) is introduced by MA, and increases the adiabatic reaction temperature sufficiently to make the reaction self-sustaining.
