Study of structure and properties of brass after repeated DRECE processing combined with heat treatment
Original language description
During last two decades great attention was paid to materials with grains of diameter smaller than 1 ?m. These materials were classified as Ultra Fine Grain (UFG) materials with diameter of grains of the order of 100 to 1000 nm and nano-materials with mean diameters of grains smaller than 50 nm. 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 brass were made on the DRECE machines to achieve grain refinement in the strip of sheet with dimensions 58 x 2 x 1 000 mm. A prototype of this equipment used has been put on Department of Mechanical Technology, VSB-Technical University of Ostrava, Faculty of Mechanical Engineering. On the part of brass strip sheets after the first DRECE processing next heat treatment 400oC/15min/air has been made to obtain the behavior of th
