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

Shear-banding is a ubiquitous plastic-deformation mode in materials. In metallic glasses,
shear bands are particularly important as they play the decisive role in controlling plasticity …

The formation of ω-phase under high-pressure torsion (HPT) has been studied in Ti–Fe
alloys. Seven alloys with Fe concentration from 0 to 10 wt% have been annealed between …

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

Abstract Ultrasonic Nanocrystal Surface Modification (UNSM) is a mechanical surface
treatment that induces large compressive residual stresses and near-surface microstructural …

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 …

Bulk metallic glasses having a disordered amorphous structure have been in the focus of
recent intensive materials research due to their special mechanical properties, however …
