Investigation of the Origin of Hot Spots in Deformed Crystals: Studies on Ammonium Perchlorate and Reference Inert Materials

Abstract

Work is in progress to investigate the roles that mechanical deformation and resultant material microstructure have on the stock reactivity of ammonium perchlorate (AP) single crystals. The deformation and fracture behaviors of AP have been studied using microindentation hardness testing. The operative slip systems and cracking planes involved in forming diamond pyramid (Vickers) impressions were identified. Using polarized light microscopy, it was determined that the strain field caused by edge dislocations surrounding the hardness impression was rather far reaching. Single crystals placed in a mineral oil bath were shocked by exploding a detonator. High-speed photography was used to observe the crystal response to the shock wave, and samples were recovered for quantitative chemical analysis of decomposition products. Keywords: Ammonium perchlorate; Hot spot; Microhardness; Polarized light microscopy; Shock reactivity; Liquid ion chromatography.
