摘要

An approach is made to quantify micro strain in energetic materials with X-ray diffraction. Samples of HMX were crystallized under varying conditions yielding different defect concentrations, and the mechanical sensitivities of the samples were measured.rnX-ray diffraction patterns were measured with varying diffraction geometry, and the widths of diffraction peaks were determined. The data were evaluated with Williamson Hall plots revealing the micro strain for each sample.rnThe investigation shows that X-ray diffraction is capable for detecting qualities of coarse crystals, when suited measuring systems are applied. Moreover, the correlation of micro strain and mechanical sensitivities gives an idea, how lattice imperfections influence macroscopic properties of energetic materials.
