Abstract

The regularities of formation of the structural properties of cast alloy AК7ч were established by deformation in isothermal conditions. The relationship between deformation intensity and structure of material was established on the base of experimental forming by the method of helical forging of workpieces, on the base of finite element modeling and metallographic investigation. It was grounded that the plasticity increases at the cost of the refinement of structure components of material.
