Powders of AlN, TiC and TiB/sub 2/ have been subjected to controlled shock loading with peak pressures in the samples between 14 to 27 GPa and preserved for post-shock study. Broadened x-ray diffraction peak profiles are analyzed by a simplified method and show increases in residual lattice strain and small decreases in crystallite size. Strain values range from 10/sup -5/ to 10/sup -4/ for TiB/sub 2/ and to values larger than 10/sup -3/ for TiC and AlN.
