Abstract

On the basis of representation of a plastic flow in the polycrystalline media in which grains and their borders interact with themselves as two diverse, but the interconnected structures, the mathematical model containing the equations of movement of continuum taking into account thermomechanical interaction of specified structures has been developed. The thermal and is intense-stress and strain condition according to model are calculated from the field equations and experimental diagrams dynamic recrystallization. The presented numeric models of the dynamic recrystalli-zation for alloy ЭИ437 and titanic alloy ВТ9, confirm the proposed setting.
