Abstract
An appreciable number of 30° dislocations could be found in plastically deformed GaP single crystals. The bending experiments were realized at an elevated temperature of 883 K. The 30° dislocations are separated into screw and 60° Shockley partials. During high-temperature deformation, stress relaxation is permitted by nucleation and motion not only of 60° and screw dislocations (both of which are separated into partials) which seems to be characteristic of III-V crystals deformed at a low temperature but also of a considerable number of glissile 30° dislocations.
