X-Ray Topographic Studies of Energetic Materials.

Abstract

The initial reports in this series of studies were concerned principally with the preparation of high quality crystalline samples of RDX, PETN and TNT for topographic examination. An analysis of the growth defect structure was carried out and the Burgers vectors of the growth defects were defined. In the present study, these examinations have been extended to the definition of the principal deformation mechanisms in PETN and RDX. This definition has come from detailed experimental and theoretical examinations of the orientation dependence of Knoop microhardness indentations on the habit faces and on cut and polished faces of the crystals, combined with etching experiments. These examinations have been supplemented by 'in situ' deformation studies coupled with X-ray topographic examination of the deformed crystals. The influence of radiation damage from the synchrotron and laboratory sources used for X-ray topographic study have been assessed. Keywords: Detonation; Single crystals; Crystal growth; Crystal perfection; Dislocations; Mechanical properties; Dislocation slip; Mechanical deformation.
