- Abstract
In this work, an experiment was conducted for obtaining ultrafine-grained state of long bars of steel AISI-321, in which the workpiece while the minimum technically possible the temperature of 800°C were rolled by a radialdisplacement rolling with a diameter of 30 mm and diameter 13 mm on the mill SVP-08. Microstructure analysis showed the presence of equiaxial ultrafine-grained structure in the peripheral areas of the workpiece and the presence of elongated fibrous texture in the axial zone. The strength of the workpiece has increased more than 2 times, while the plasticity has decreased not so much. The study of microhardness distribution showed a smooth decrease of 10.2 % from the periphery to the center of the produced sample, with an overall growth of microhardness of 2 times relative to the original.
