Despite its promise, the use of nanostructured metals and alloys as a new generation of
structural and functional materials has only recently been realized. Only in recent years has …

High-pressure torsion (HPT) was applied to discs of pure Ti and Zr under pressures of 2 and
6 GPa, and the evolution of electrical resistivity was investigated. The electrical resistivity …

During extrusion, the material is subjected to a heterogeneous deformation that results in the
formation of gradients of microstructure and thus mechanical properties. In this study, using …

Equal channel angular pressing (ECAP) was used to process Mg-4Zn-1Mn alloy at 300° C
using route B c up to 4 pass with a cumulative strain of 3.2. Optical microscope (OM) …

Solid‐state welding of Al 1043 sheets was achieved via high‐pressure torsion (HPT)
processing to produce bulk nanostructured Al disks. A homogeneous nanostructure without …

Structural inhomogeneities along the axial, and not only the radial, direction are shown to
occur in Zr 3 Al deformed by high-pressure torsion (HPT) at room temperature. Scanning …

Deformation microstructures of an Fe–15% Cr ferritic stainless steel during cold working to
strains above 7 were studied. Two processing methods, unidirectional working consisting of …

Severe plastic deformation (SPD) is a method of converting coarse grained metals into
ultrafine grained metals, which possess improved mechanical and physical properties …

The processing of polycrystalline metals through the application of severe plastic
deformation is attracting much attention because of the potential for achieving significant …

The high-temperature thermal stability of the ultrafine-grained (UFG) microstructures in low
stacking fault energy silver was studied by differential scanning calorimetry (DSC). The UFG …
