Abstract

Diamond nanosize powders were treated at pressures ranging from 2.0 to 8.0 GPa at a constant temperature of 1470 K. X-ray diffraction peak profiles of treated samples were analyzed and provided information on the average crystallite sizes and the density of the dislocations. The population of dislocations increased with applied pressure while the average crystallite size did not change significantly.
