The grain size, and therefore the grain boundary density, is known to play a major role in the
flow stress of metallic materials. A linear relationship to the inverse of the square root of the …

The tensile elongation behavior and deformation mechanisms of superplastic Mg alloys and
Mg composites were examined by extensively reviewing the literature published from the …

Abstract A ZK60A magnesium alloy was processed by high-pressure torsion (HPT) at room
temperature at compressive pressures up to a maximum of 6.0 GPa for up to 5 revolutions …

In this study, we are pleased to report a low-alloyed Mg–1.0 Zn–0.45 Ca–0.35 Sn–0.2 Mn
(wt.%) alloy sheet fabricated by hot rolling, showing superplastic deformation ability with …

An AZ31 magnesium alloy was processed by high-pressure torsion (HPT) at room
temperature under an imposed pressure of 6.0 GPa. Microstructural analysis showed that …

Processing through the application of severe plastic deformation (SPD) is attractive because
it produces significant grain refinement and high strength. The standard procedure for …

Friction stir processing (FSP) was used to refine the microstructure of cast AZ91 magnesium
alloy. Superplastic tensile behavior of the fine-grained AZ91 was investigated by means of …

In the current study, parallel tubular channel angular pressing (PTCAP), as a severe plastic
deformation (SPD) method, was applied on a commercial pre extruded Mg-3Al-1Zn (AZ31) …

Microstructure and tensile behaviors of AZ31 magnesium alloy prepared by friction stir
processing (FSP) were investigated. The results show that microstructure of the AZ31 hot …

Equal-channel angular pressing provides an opportunity for refining the grain structure and
introducing superplastic properties in magnesium alloys. This report describes the use of …
