The rheological model of deformation nidus in the process of rolling

On the basis of contemporary ideas on the metal pressure shaping theory and investigation results of the metal stress-stained state during rolling and using variation principles of mechanics, the plastometric classification of metals and alloys, a new rheological model of the high deformation nidus is proposed in this work. The model explains the regularities in the distribution of plastic deformation intensity in the non-contact zones as well as the formation of the feed front end deformation in dependence of the plastometric properties of metals. Experimental data conforming the validity of the model are given also.
