In the preparation of PBX 9501 samples, pressing conditions are often varied in order to achieve nominal density. Although density is met, differences in pressing intensity can lead to variations in microstructure between samples. To evaluate the effect of pressing intensity on the microstructure, three cylinders (1-inch {phi} x 1-inch long) of PBX 9501 (HOL Lot 89C730-010 MT 345) have been pressed at 5,000 psi, 15,000 psi, and 30,000 psi, respectively, using a 50 Ton press. Following pressing, the entire profile of each cylinder was examined for microstructural changes due to the different pressing conditions. As differences in material microstructure can occur across a wide range of length scales (from nanometers to millimeters) both polarized light microscopy and small-angle x-ray scattering (SAXS) have been used to probe the particle morphology, porosity, crystal size and size distribution of each cylinder.
