This paper presents the results obtained from the structural refinement of selected metals and alloys produced by severe plastic deformation processes. Large levels of deformations were produced using four methods, which differed in the character and dynamics of the loading, as well as in the intensity and homogeneity of the plastic strain field. Qualitative and quantitative studies of the refined microstructure were carried out using stereological and computer image analytical methods. Microhardness and selected mechanical properties, such as strength and yield point, were also determined.
