Effect of thermomechanical treatment on flow behaviour, microstructure and texture development of aluminium alloy in semisolid state

In the present work, an ingot of a commercial aluminium alloyAl-8Si-0.25 Mg, was deformed by rolling ; a second ingot was extruded ; and a third was cast in such a way as to obtain fine sized dendrites. Simple compression experiments (parallel plates) showed that for high solid fractions (0, 70) the extruded material exhibited the highest deformation response among specimens, but when the solid fraction was lower (0, 60) the deformation behavior of as cast, extruded, and rolled specimens was similar.
