Abstract: Radial-shear rolling (RSR) technology is the most promising and effective way to produce various high-quality long-length metal products from ferrous and non-ferrous metals and alloys, including those with a gradient ultrafine-grained structure. RSR scheme has one main difference from the well-known cross–screw rolling scheme - an increased feed angle α = 18°-20°. In this case, the rolling angle β remains in the range from 5 to 7°. Based on this scheme (i.e., the RSR scheme), a number of radial-shear rolling mills were developed and put into small-scale production. In this paper, we review our team’s experience in using the radial-shear rolling method to improve the structure and properties of various ferrous and non-ferrous metals and alloys. The review of scientific publications of our team in this area given in this article indicates the prospects of using RSR technology to produce high-quality metal products with a given level of properties.
