In this paper, we present the experimental results of complex studies of the sensitivity to mechanical effects and detonation parameters of metalized explosive compositions based on weakly phlegmatized HMX and RDX. Powders of titanium, zirconium, and their hydrides and deuterides were used as fillers. The introduction of these components in an amount of up to 20 wt % is established to contribute to some increase in fire hazard and sensitivity of the compositions in handling them. Estimates show that an increase in the detonation parameters of the mixtures observed in some cases may be due to the chemical reactions of the additives with explosion products in the detonation wave front.

Two explosive compositions ISU-4K and ISU-5R based on ammonium nitrate with added coke, diesel fuel, and rubber crumbs are tested so as to establish their sensitivity to mechanical and thermal perturbations. The flash point corresponding to 60-s delay is established. The kinetic parameters of thermal disintegration of the explosives are determined. The information obtained may be used in compiling standard documents (of GOST, OST, TU, VTU, and other types) and writing industrial regulations.

@Abstraction limits of flame propagation are determined for 13 glycols, as well as their enthalpy of formation and enthalpy of combustion. These characteristics depend on the number of carbon atoms in the glycol molecule. The combustion parameters are calculated for vapor–air mixtures of glycols and monoatomic alcohols, in the case where P = 1 atm and V = const. The adiabatic combustion temperature of mixtures of limiting and stoichiometric composition does not depend on the number of hydroxyl groups in the alcohol molecule. The explosive pressure of glycol is slightly higher than for monoatomic alcohols.

The theoretical basis of laboratory shock sensitivity test procedures (methods of critical energies and critical pressures) of energetic materials is given. The quantitative criterion of explosive risk has been introduced and calculated by the example of model hydrogenous explosive material.
