Diffraction peak broadening of energetic materials

The peak broadening of a series of energetic materials was measured at the synchrotron ANKA, and the results were evaluated by means of Williamson-Hall-plot and the double Voigt approach yielding mean crystallite size and micro strain. The investigations revealed characteristic anisotropic peak broadening which is discussed in relation to prevailing twin and dislocation slip systems. Besides, the concentration of amorphous HMX impurities was found to correlate with the peak broadening of RDX.
