Method of treating solids with high dynamic pressure
Abstract
Abstract A PROCESS FOR TREATING SOLID MATERIALS WITH CONTROLLED, VERY HIGH, DYNAMIC PRESSURES ALL OR A PORTION OF THE TOTAL PRESSURE RISE OCCURING IN A SHOCK COMPRESSION AND ANY REMAINING PORTION OCCURING AS A SMOOTH, RAPID (NONSHOCK) COMPRESSION, THE PRESSURE BEING RELEASED SMOOTHLY TO AMBIENT CONDITIONS, COMPRISING SUBJECTING THE LATERAL BOUNDARIES OF A BODY OF A SOLID MATERIAL TO A PRESSURE PULSE MOVING AT PRACTICALLY CONSTANT VELOCITY IN THE DIRECTION OF THE BODY''S AXIAL DIMENSION AND HAVING PRACTICALLY UNIFORM MAGNITUDE AND DURATION OVER THE LATERAL BOUNDARIES, THE MAGNITUDE AND DURATION BEING SUFFICIENT TO SUSTAIN A SHOCK WAVE OF SUBSTANTIALLY UNIFORM INTENSITY SPANNING A MAJOR PORTION OF THE BODY BETWEEN THE LATERAL BOUNDARIES. THE PROCESS IS USEFUL IN CONVERTING NONDIAMOND CARBON TO DIAMOND AND HEXAGONAL BORON NITRIDE TO CUBIC AND WURTZLIC BORON NITRIDE AND IN COMPACTING SOLID MATERIALS SUCH AS SILICON CARBIDE POWDER.
