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 past decade was marked by significant advances in the development of severe plastic
deformation (SPD) techniques to achieve new and superior properties in various materials …

Superplastic deformation of polycrystalline materials is usually accommodated by diffusion-
assisted grain boundary (GB) sliding at high temperatures. Lowering the temperature …

Advanced structural materials are expected to display significantly improved mechanical
properties and this may be achieved, at least in part, by refining the grain size to the …

The effect of homogenization process on the microstructure evolution and mechanical
properties of Al-Cu-Li alloys with various Cu/Li ratios (ranging from 2.4 to 3.7) are studied …

The superplastic forming technique, which realized extremely high plastic deformation, is
used for producing complex shaped lightweight constructions. Physical models and …

Abstract Al-Mg alloys (AA5083-type) are widely used for superplastic forming. Limited grain
boundary sliding as compared to other superplastic alloys limits the formability of Al-Mg …

In this paper, the effect of grain sizes on mechanical properties and microstructure evolution
of pure Al sheet at cryogenic temperatures were studied by uniaxial tensile tests and …

The ability of a material to stretch in tension is strongly influenced by the strain rate
sensitivity and this parameter plays an even bigger role during deformation of ultrafine and …

Homogeneous nanostructured and ultrafine-grained states in an Al-Mg-Mn-Zn-Zr alloy were
produced by high pressure torsion at room temperature and by continuous equal channel …
