Mechanistic processes controlling the shock-induced chemical reaction behavior of highly reactive Ti-Si and Ti-B powder-mixtures were investigated. Recovery experiments were performed, using Sandia Bear fixtures, to determine the reaction initiation thresholds for the respective systems, and to produce compacts of unreacted states to characterize the shock-compressed configuration of reactants at conditions below the reaction threshold. X-ray diffraction line broadening and scanning electron microscopy analysis were used to determine the response of individual reactants during shock-compression. It was observed that the deformation and/or fracture response of reactants during shock-compression influences the threshold conditions for, reaction initiation and the overall reaction propensity.
