摘要
The weakening in cyclic deformation of a strongly deformed wire of nonalloy low-carbon steel is investigated; it is presumed to be associated with the formation of a mixed dislocational and disclinational substructure. The dependence of the degree of athermal weakening on the structural state of the steel prior to drawing is shown. The correlation between the strengthening in cyclic deformation and the intensity of preliminary strengthening in drawing (in terms of the yield point and coercive force) is established.
