A novel severe plastic deformation method entitled rolling with cyclic movement of rolls was proposed to fabricate ultrafine grained CuCr0.6 copper alloy. The alloy in the solution treated conditions was processed by rolling with cyclic movement of rolls method by using process parameters as amplitude of rolls movement (A = 0.9 mm), frequency of rolls movement (f = 1 Hz), rolling reduction (ε_{h} = 50%) and rolling rate (v = 1, v = 2, v = 3 rpm). Light microscopy, scanning electron microscopy and a electron backscattering diffraction detector, and scanning transmission electron microscopy were used for microstructural characterization, and hardness tests for a preliminary assessment of mechanical properties. Quantitative studies of the average diameter of the subgrains d (μm) and the average diameter of the grains D (μm) were performed using the scanning electron microscopy/electron backscattering diffraction method. Misorientation angles were analyzed by the Kikuchi-line technique using TSL-OIM software. The results show that the samples underwent very high strain at the lateral areas and smaller at the central areas. As a result, the microstructure became heterogeneous and remained unchanged with change in compression rate. The transverse movement of rolls causes in the material significant effect of refining structure in peripheral areas of sample.

The results of the microstructure investigations of the pure Al and AlMg5 alloy and pure Cu and CuFe2 alloy after the application of severe plastic deformation implemented by rolling with the cyclic movement of the rolls are presented in this paper. The rolling with the cyclic movement of the rolls was carried out at values: the rolling rate v=1 rpm, the frequency of rolls movement f=1 Hz, the amplitude of rolls movement A=1.6 mm. Maximal values of rolling reduction at 6 passes was ε_{h}=80%. The structure of the these materials was analyzed using scanning transmission electron microscope. The quantitative studies of the substructure was performed with MET-ILO software, on the basis of images acquired on scanning transmission electron microscope. Performed substructure investigations showed that using the rolling with the cyclic movement of the rolls method can refine the microstructure of these materials to the ultrafine scale.

The results of microstructure and hardness investigations of the CuFe2 and CuCr0.6 alloys after solution and ageing treatment are presented in this paper. The variants of heat treatment as: solution at 1000°C per 3 h and ageing treatment at 500°C for 2 h and at 700°C for 24 h were chosen for severe plastic deformation process realized by rolling with the cyclic movement of rolls method. The structure of CuFe2 and CuCr0.6 alloys was analysed using scanning transmission electron microscopy, and the quantitative studies of the substructure was performed with MET-ILO software, on the basis of images acquired on scanning transmission electron microscope.
