Inhomogeneities in structure and chemistry can play a significant role in the overall response of materials under shock compression. Understanding this link between configuration and response is the key to developing novel, microengineered materials with tailored mechanical/chemical behavior. In this talk, I will describe the effect of intrinsic (melt temperature, density, yield strength) and extrinsic properties (particle size, shape, orientation) on the behavior of powder mixtures, with attention to the initial densification response and subsequent reaction initiation. Following the collective work on silicide- and aluminide-forming mixtures, I will also present a conceptual framework for shock-induced reactions, which may be used to guide development of energetic systems with tailored chemical response.
