Abstract
Dislocation loops in graphite have been observed to exist in both unsheared and sheared orientations. It is believed that shear is caused by the cleavage of the material for electron microscope examination, and a mechanism involving this is theoretically examined and shown to explain the observed characteristics of sheared loops. It is concluded that the ‘A over A’ stacking-fault energy is 38 ergs cm-2, and that the lattice strains around vacancy loops of radius <100 Å are not characteristic of perfect dislocation loops.Keywords
