Structure and properties of copper after DRECE processing
Original language description
This research concerned the whole production of UFG materials, using Severe Plastic Deformation (SPD) method. One of them is new type of equipment DRECE (Dual Rolling Equal Channel Extrusion), designated for obtaining UFG structure in strip of sheet. Experiments with use of material Cu 99.5% were made on the DRECE machines in order to achieve grain refinement in the strip of sheet with dimensions 58 x 2 x 1 000 mm. For orientation information, whether grain was refined preliminary metallographic analysis was made on optical microscope NEOPHOT 2. Structure was analysed on the surface in longitudinal direction in respect to direction of rolling, and also in cross section and longitudinal section. Altogether to 10 passes were made through the DRECE tool.Comparison was made for initial state and for the state after the third pass.
