Objective of the first part of the program was to investigate the shock activation of titanium carbide, titanium diboride, aluminum nitride and aluminum oxide powders using the cylindrical geometry. A series of shock activation experiments was conducted in which the starting temperature of the material was the major variable. The effect of temperature on the defect structure created when the sample was subsequently shocked was investigated. Emphasis was then shifted to the direct consolidation of the selected powders. Again the cylindrical configuration was chosen and the initial temperature was the major variable. In both cases, the shock wave was created by detonating a uniform layer of powdered explosive which surrounded the sample container. The explosive layer is simultaneously initiated around the periphery of the cylinder at one end. The circumferential shock front thus progressed axially along the sample container wall.
