Abstract

In order to investigate the evolution of strain states during screw rolling, the samples of pure copper rod were rolled in a three-roll screw rolling mill. Microstructure observations and hardness measurements were carried out for examining the deformation during screw rolling. In addition, the finite element method (FEM) was employed to calculate. The strain states reveal that the shear strain plays a dominant role in the deformation during screw rolling.
