Severe plastic deformation (SPD) is effective in producing bulk ultrafine-grained and
nanostructured materials with large densities of lattice defects. This field, also known as …

Severe plastic deformation (SPD) can induce various phase transformations. After a certain
strain, the dynamic equilibrium establishes between defects production by an external force …

Ultrafine-grained and heterostructured materials are currently of high interest due to their
superior mechanical and functional properties. Severe plastic deformation (SPD) is one of …

Severe plastic deformation (SPD) has been widely studied in order to enhance the strength
and ductility of metallic materials. Among various SPD processing techniques, high-pressure …
