Abstract

Shown that the processes of heat generation and distribution of carbon steel during the deformation are interrelated. Plastic deformation causes a redistribution of carbon in various locations of the deformed volume. Areas with large plastic deformations have a higher carbon content. At these sites during the deformation of the rod is more intense heat buildup. Sources of heat are thermochemical processes associated with the migration of carbon between dislocations and carbonsteel components. We present experimental data.

Keywords
