The mechanisms of the processes occurring during the explosive crushing and softening of pieces of solid tungsten-cobalt alloys are considered. The parameters of the stress field required for their effective destruction are recorded. The estimation of the duration of the process of destruction in a given section of the explosive charge is carried out. A method is proposed for calculating the A and m coefficients in the Theta impact shock compressibility equation for tungsten-cobalt alloys and their value for the TC8 alloy is obtained. The parameters of strong compression waves in the TC8 alloy and steel at pressures in detonation products of 5 and 1 GPa are estimated in cases of perpendicular and tangential wave incidence on the surface of the piece. The analysis of the processes occurring in a steel pipe filled with explosives and pieces of TC8 alloy was carried out. The work obtained the results needed by experimenters and explosives practitioners for developing designs of crushing charges for pieces of tungsten-cobalt alloys.

Shock Compressibility

AbstractUltra-fast reactions initiated within or immediately behind the shock front in powder mixtures are of importance in the synthesis of high-pressure phases and next-generation energetic materials. Reactions in nickel and aluminum powder mixtures and the establishment of a reaction threshold have been the source of many studies over the last 20 years. Prior work has suggested that the criterion for reaction is most probably mechanochemical in nature, in which shock loading environment plays a larger role than absolute shock energy input. The mechanisms responsible for intimate mixing of fresh reactants are however still unclear. In this work we are investigating the role of particle size and morphology on the loading, mixing, and their subsequent shock-induced reaction behavior, by performing shock-compressibility experiments on equi-volumetric mixtures of nickel and aluminum powders, with variations in nickel particle size (micron and nano-scale) and shape (spherical and flake). Determination of shock states is accomplished through time-resolved in situ PVDF gauge measurements of input shock stress and shock propagation speed obtained from transit time through the thickness of powder mixture. The reaction product shock-compressibility state is also being calculated based on constant pressure approximations to allow correlation with measured states for inference of the occurrence of shock-induced chemical reactions. The results of this study suggest that powder configuration in the nickel-aluminum system can be modified to encourage or discourage reaction.
