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

High-pressure torsion (HPT) method currently receives much attention as a severe plastic
deformation (SPD) technique mainly because of the reports of Prof. Ruslan Z. Valiev and his …

Archean passive margins. In When Did Plate Tectonics Begin on Planet Earth?(eds KC
Condie & V. Pease.), pp. 149–56. Geological Society of America Special Paper no. 440 …

Severe plastic deformation (SPD) has established itself as a potent means of producing bulk
ultrafine grained and nanostructured materials. It has given rise to burgeoning research that …

The evolution of microstructure and the mechanical response of copper subjected to severe
plastic deformation using equal channel angular pressing (ECAP) was investigated …

Disks of an Al–3% Mg–0.2% Sc alloy were processed by high-pressure torsion (HPT) to
refine the grain size to∼ 0.15 μm. Inspection of the disks after processing revealed a central …

Experimental data show that the conventional Hall-Petch relationship cannot be maintained
in its original form for metals having submicrometer structures. We now propose a …

A reliable and accurate description of the constitutive behavior of metals under the coupled
effect of extremely high strain rate has become more and more important. The conventional …

By means of dynamic plastic deformation (DPD) at liquid nitrogen temperature (LNT), bulk
nano-grained copper samples with embedded nano-twin bundles were prepared …

Experiments were conducted to examine the influence of equal-channel angular pressing
(ECAP) on the development of precipitation microstructures in two supersaturated Al–Zn–Mg …
