The authors consider the refinement of the microstructure of copper (grade M1) on the rate of deformation using a “helical rolling-pressing” method. The deformation was performed at 500°C. It was shown that high intensity of the shear deformations characteristic of helical rolling and a combined process of “helical rolling-pressing” allows for a significant grain refinement. The minimum grain size is obtained when the mill rolls rotate at 120 rpm.
