Abstract : Synthesis of materials by shock-induced chemical reactions (shock chemistry) has in recent years, evolved from the stage of curiosity-driven and proof-of-concept experiments, to the need for developing a fundamental understanding of this unique but complex process. The unusual combination of pressure and temperature states that produce the large plastic deformations, are only singularly possible during shock-compression. Shock chemistry can, thus, be applied for synthesis of metastable phases, non-stoichiometric compounds, and modified microstructures. The complex nature of the reaction process-mechanisms and kinetics, has however, been only recently realized. It is therefore essential to obtain a complete understanding of the fundamental mechanistic and kinetic aspects of processes responsible for shock-induced reaction chemistry. This proceedings includes abstracts and viewgraphs/papers of talks presented during the four topical sessions: Shock-compression Principles; Real-time In-situ Measurements; Mechanistic Issues Associated Processes; and Shock-Synthesis Applications and Process Mechanisms.
