Abstract
There are a significant number of physical and chemical impact methods for the metallic materials during the processes of crystallization, deformation, and heat treatment, leading to the refinement of the structure. However, traditional technologies for the fabrication of metallic materials often result in the coarse-grained structure, as most of them employ processing temperatures, at which the resulting small grains are unstable. From the severe plastic-deformation point of view, traditional rolling has a significant drawback, limiting its use for obtaining the ultrafine-grained structure in materials. Thus, total accumulated deformation is limited during conventional rolling by the multiple decreases in rolled blank thickness. In this regard, in recent years, several specialized rolling methods, which allow eliminating this drawback, were proposed.
Keywords: rolling, severe plastic deformation, ultrafine-grained structure, microstructure.
