Abstract

The paper contains theoretical and experimental studies of structural changes during hot deformation of the metal-bound process of controlled rolling. The effect of preheating temperature and the degree of deformation on the austenite grain size was studded. Diffraction methods to determine the parameters of the polygonal structure formed during hot deformation and shows the quantitative changes in her period after deformation was used. The nucleation of recrystallized in poligonized ferrite, as well as the nature, structure and properties of special boundaries in terms of lattice theory of coincident sites was considered.
