VACANCIES AND DISLOCATION LOOPS IN GRAPHITE
Electron microscope studies were undertaken to determine concentrations and mobilities of vacancies in graphite. Crystals were quenched and annealed to various temperatures. Crystals under strain (some deliberately bent) before heat treatment contained larger numbers of loops while crystals treated under strain- free conditions showed no loops. Crystals quenched from 3000 deg C showed no loops even when bent or irradiated with neutrons, indicating that loops are not produced by coalescing of excess quenchedin vacancies. (D.C.W.)
