Microstructures and Mechanical Properties of Steels and Alloys Subjected to Large-Strain Cold-to-Warm Deformation

The effect of large-strain cold-to-warm deformation on the microstructures and mechanical properties various steels alloys is critically reviewed. review mainly focused microstructure evolution, whereas textures are cursorily considered without detailed examination. in a wide strain range, from early straining to severe deformations. Such an approach offers clearer view how mechanisms affect structural changes leading final evolved large strains. general regularities evolution shown for different methods, including conventional rolling/swaging special techniques, such as equal channel angular pressing or torsion under high pressure. microstructural during deformations processing conditions functions total strain. Then, some important mutual relationships between parameters, e.g., grain size vs. dislocation density, revealed discussed. Particular attention paid that responsible refinement. development ultrafine-grained terms continuous dynamic recrystallization. latter discussed comparison with (discontinuous) recrystallization subdivision (fragmentation) phenomenon. structure–property relations quantitatively represented strengthening, taking into account retardation.
