Break Up

A study has been made of the combustion and explosion of single crystals of a number of compounds. These include the styphnates, fulminates and azides. A high-speed ciné microscope developed by Courtney-Pratt has been used. This enables magnified pictures of events lasting several milliseconds to be recorded. Crystals which have faults break up during combustion, and particles fly off at high speed. When the crystals are relatively free from faults the combustion may be followed along the length of the crystal and burning speeds may be measured. A variation in speed with crystal size and initial temperature has been observed, and this is discussed in relation to thermal losses during burning. The combustion of cyanuric triazide under water has also been recorded. The behaviour of the compounds such as silver and thallous azide which can melt is different from that of crystals which explode without melting. The effect of crystal size on the development of combustion and explosion is discussed with particular reference to silver azide.

AbstractDeformation of cyclotrimethylenetrinitramine (RDX) and ammonium perchlorate (AP) crystals at low strain rates was studied by diamond pyramid (Vickers and Knoop) microindentation hardness testing. RDX is two to three times harder than AP and has relatively limited slip system activity. While both crystals readily crack, cracking did not reduce hardness in RDX but did in AP. Strain fields surrounding the hardness impressions in RDX were extremely localized while in AP they extended well beyond the impressions. Shock experiments were conducted on large (5–9 mm), single crystals in a fluid-filled tank designed to permit high-speed photography and sample recovery. Reaction threshold was obtained by varying the shock pressure entering the crystals. Shock-entry orientation and large hardness impressions were used to alter microstructural responses. High-speed photography showed luminous crack propagation and reaction in both materials and the same slip deformation in AP as from hardness testing. Orientation affected the microstructural response and reaction threshold for AP, and hardness impressions sensitized chemical decomposition far from the impressions. Recovered AP crystals were much more plastically deformed than RDX crystals and were often still transparent in the region opposite shock entry. Recovered RDX crystals, at even the lowest shock pressure of 8.6 kbar, were uniformly white from a high density of fine cracks. RDX reaction threshold was ∼62 kbar versus 17 to 24 kbar for AP, depending on crystal orientation to the shock wave.
