In graphite, unlike other crystals, the structure of dislocations is such that there is only a distortion of the layers of hexagons and neither free bonds nor jogs are associated with edge dislocations in the basal plane. An electronoptical study of quenched-in vacancies in graphite showed possibly a preferential condensation of vacancy loops in the stacking fault ribbons of the widely dissociated dislocations. It is shown that the disappearance of vacancies, i.e., the extension of the loops, is accompanied by glide of the partial dislocations, rather than climb: the prismatic dislocation climbs. It is suggested that the precipitation process contributes to the quench hardening and radiation hardening of graphite. (L.T.W.)
