“…The existence of these situations has been shown for detonations of explosive mixtures with inert additives [8,9]. The heterogeneous alloys considered in the present paper differ in that both components are explosives capable of fast self-sustained decomposition.…”

The effect of the particle size of HMX in alloys with TNT on the synthesis of nanodiamonds in a detonation wave was studied experimentally. Mixtures with a TNT content of 40 to 90% and the specific surface area of HMX varied in the range of 5-510 m 2 /kg were investigated. For all mixtures, an increase in the particle size of HMX was found to lead to an increase in the yield of nanodiamonds with the maximum yield shift toward alloys with increased TNT content. The results are explained using a model based on the absence of thermodynamic equilibrium between the components of the heterogeneous explosive during detonation.

“…Results showed that the detonation speed decreased as the TiH 2 content increasing, when TiH 2 particle size was relative big. It indicated that big size TiH 2 particle did not react in the detonation zone, since thermal equilibrium was not achieved in this case[11]. Hence, the detonation of big size TiH 2 /RDX explosive followed the mixed reaction mechanism and heat dilution theory.…”

Particle distribution of titanium hydride (TiH2) during the ball mill process was studied by milling it with different time. Scanning electron microscope (SEM) pictures showed that particle size decreased quickly at the initial stage, and homogeneous, super fine TiH2 powder was obtained after 4 h mill. Application of TiH2 in energetic materials was investigated by preparation of TiH2/RDX composite explosive and measuring the detonation speed. Results showed that detonation speed of TiH2/RDX explosive was depended on the content and particle size of TiH2. TiH2 is a potential additive in high explosives (HE).

“…There are different viewpoints on this problem (see [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] and the references therein). Most researchers believe that the additive reacts in the phase of strong expansion of detonation products.…”

A method of electrical conductivity and an analysis of recovered explosion products are used to study interaction of aluminum with detonation products of condensed high explosives. The electrical conductivity of HMX/Al and RDX/Al mixtures is inhomogeneous; a region with the maximum electrical conductivity is adjacent to the detonation front, whereas the electrical conductivity decreases with distance from the front. If the wave is incident onto a wall, the electrical resistance of the composite high explosive increases, which indicates that the high-conducting zone disappears. The electrical conductivity, resistance of the conducting zone, and the time of resistance growth are found as functions of the particle size of the additive. The results obtained confirm the reaction of the metal additive with detonation products in a microsecond range of time. An analysis of condensed explosion products shows that the reaction of aluminum with detonation products proceeds on the particle surface. The amount of reacted aluminum and the oxide-layer thickness are estimated.
