Considering the Deformation behavior of Al6061-T6 under Equal Channel Angular Swaging (ECAS)

Equal channel angular swaging (ECAS) is a new severeplastic deformation (SPD) method which is based oncombination of ECAP and incremental metal formingprocess of rotary swaging. In this article deformationbehavior of a 10 mm diameter Al 6061-T6 bar under ECAShas been considered by means of numerical simulations andexperimental investigations. The results revealed that theradial and axial forces obtained by FE simulations areunderestimated and overestimated respectively incomparison with the derivatives from analytical formulas.According to the workpiece deformation that is acombination of bending and shear, these deviations could berelated to reduction of the friction force which pulls theworkpiece into the channel.
