Peculiarities of the dislocation structure of zinc originating under the effect of laser beams

Results obtained in a study of the dislocation structure of zinc subjected to the effect of a laser beam are described in this paper. The difference in the location of dislocations after concentrated mechanical, thermal, and laser deformation is established. This indicates the possibility of different plastic deformation mechanisms under the mentioned kinds of effects Bending of the crystallographic planes because of deformation of the crystal surface by the laser beam is detected. The volume distribution of dislocations and their behavior at different temperatures are studied.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 4, pp. 26–30, April, 1976.
