Nano- and submicrocrystalline structure ; severe plastic deformation (SPD)

Sažetak
Now it is well established that severe plastic deformation (SPD) at low temperatures leads to ultra-fine grained structure with grain size of nano- and submicro-scale. This structure determines enhanced mechanical and unusual physical properties. Our presentation is aimed to consider the formation of nano- (d < 100 nm) and submicrocrystalline structure (100 nm < d < 1000 nm) in steels during SPD by torsion under high pressure and equal channel angular pressing. Structure formation dependencies on temperature deformation conditions, strain degree, chemical composition, initial state and pressure are considered. The role of phase transformations for additional grain refinement, namely, martensitic transformation, precipitation and dissolution of carbide particles during SPD and others, is underlined. Mechanical properties of several steels made by SPD are compared in relation to their structure and discussed.
