Microstructural features, such as defects, crystal morphology, and crystal size distribution, can significantly affect the ignition sensitivity, performance, and mechanical properties of energetic materials. To evaluate the influence of pressing parameters on microstructure, three cylinders of PBX 9501 were pressed at 5,000, 15,000, and 30,000 psi, using a 100 ton heated steel die press. Polarized light microscopy images taken at 144 locations within each cylinder show differences in porosity, crystal size, and crystal size distribution between cylinders and at different locations within the same cylinder. Scanning electron microscopy further verifies increased fracture and pulverization of HMX crystals during pressing.
