Among the severe plastic deformation processing (SPD) of materials, high-pressure torsion
(HPT) is known to induce considerable amounts of plastic strain and crucial grain refinement …

Microstructural characteristics and enhanced mechanical properties of 2024 aluminum alloy
associated with shot-peening treatment were investigated by optical microscope (OM) …

High-pressure torsion (HPT) is an attractive processing method in severe plastic deformation
techniques involving the application of high compressive pressure with concurrent torsional …

Severe plastic deformation (SPD) always leads to the strong grain refinement in the
materials. Logically, in two-and multiphase alloys SPD has to cause the fragmentation and …

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

The present investigation was conducted to study the microstructural, mechanical and
texture evolutions of a 7075 aluminum alloy at the early stage of severe plastic deformation …

The important class of grain boundary (GB) complexions includes the few nanometer thick
layers having composition which strongly differs from that of the abutting grains. Such GB …

The high-pressure torsion (HPT) of binary copper alloys with 3, 5, 8, 10 wt.% Ag and 14 wt.%
Sn has been studied at room temperature T HPT. Before HPT, the Cu–Ag alloys have been …

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 …
