Shock Wave Interactions with Exothermic Mixtures
Abstract
Instrumented high velocity impact recovery experiments were performed to study solid state reactions in mixtures of nickel and aluminum powders during the passage of shock waves. 'Excess pressure' due to the release of energy from the exothermic reaction was measured for a range of impact velocities. An impact velocity threshold for the initiation of reaction at the reflected shock front was established and this threshold value was found to be dependent on the particle size of the powder. Microscopic examination of the recovered specimens show features which corroborate hypothesized extent of reaction based on pressure measurements.
