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 …

Ultrafine-grained and heterostructured materials are currently of high interest due to their
superior mechanical and functional properties. Severe plastic deformation (SPD) is one of …

The CoCrFeNiMn multicomponent is one of the most widely and best studied of all high-
entropy alloys (HEAs) since its exceptional properties suggest potential uses as a structural …

Nanostructured metallic materials having nanocrystalline and ultrafine-grained structures
show exceptional mechanical properties, eg superior strength, that are very attractive for …

High strain rate superplasticity by the friction stir processing (FSP), an adaptation of the
friction stir welding (FSW), is summarized in this overview article. As a common severe …

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 …

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 …

High-pressure torsion (HPT) refers to the processing of metals whereby samples are
subjected to a compressive force and concurrent torsional straining. Although the …

Ultrafine-grained materials display almost no strain hardening, an enhanced strain rate
sensitivity and grain boundary offsets during plastic deformation. It is expected that …

On this seventy-fifth anniversary of the first scientific report of true superplastic flow, it is
appropriate both to look back and examine the major developments that established the …
