Structure-related property changes in polycrystalline graphite under neutron irradiation

Abstract The properties of polycrystalline graphite are related to those of their component crystallites by structure-dependent factors. Neutron irradiation changes the properties of the crystals and indirectly the “structure factors” that relate the macroscopic to the microscopic properties. It is proposed and demonstrated that each of these structure factors depends upon a single parameter XT, defined as the difference in the crystal dimensional changes parallel and perpendicular to the hexagonal axis.
