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 …

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 …

The present work focuses on the friction stress and the Hall-Petch relationship in CoCrNi
equi-atomic medium entropy alloy (MEA). The CoCrNi equi-atomic MEA and a Ni-40Co alloy …

This article presents our take on the area of bulk ultrafine-grained materials produced by
severe plastic deformation (SPD). Over the last decades, research activities in this area have …

Friction stir welding (FSW), a highly efficient solid-state joining technique, has been termed
as “green” technology due to its energy efficiency and environment friendliness. It is an …

Twenty-five years ago, in 1988, there appeared a classic description of the application of
severe plastic deformation (SPD) to bulk solids in order to achieve exceptional grain …

Pure tungsten and tungsten alloys with minor alloying additions are known to be brittle at
room temperature and have high ductile-to-brittle transition temperatures (DBTT). Improving …

In recent years, much progress has been made in the studies of nanostructured Al alloys for
advanced structural and functional use associated both with the development of novel …

Interstitial-free (IF) steel with ultrafine-grained (UFG) size was used to clarify the underlying
mechanisms of the 'extra-hardening'behavior from the Hall-Petch plot and the discontinuous …

In recent years, bulk nanostructured materials (NSM) processed by methods of severe
