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 …

Abstract Bulk nanostructured (ns)/ultrafine-grained (UFG) metallic materials possess very
high strength, making them attractive for high strength, lightweight and energy efficient …

Rare-earth metals create unique opportunities in improving properties of aluminum alloys.
For over a century, there have been attempts to explore cerium for aluminum alloying …

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

Heavy plastic shear deformation at relatively low homologous temperatures is called high-
pressure torsion (HPT) deformation, which is one method of severe plastic deformation …

Severe plastic deformation can lead to the phase transformations in the materials. Even the
severe plastic deformation at ambient temperature is frequently equivalent to the heat …

The objective of this work is to prove whether the concept of effective temperature is
applicable to the severe plastic deformation (SPD). This concept was originally developed …

During severe plastic deformation (SPD), a steady-state is usually reached after a certain
value of strain (ie number of passes during equal-channel pressing or number of rotations …

During severe plastic deformation (SPD), the processes of lattice defect formation as well as
their relaxation (annihilation) compete with each other. As a result, a dynamic equilibrium is …

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 …
