The fine-grained microstructure required for superplasticity in commercial aluminium alloys is developed in one of two ways. In alloys such as AA5083 Al-Mg-Mn and AA7475 Al-Zn-Mg-Cr, static recrystallisation produces an equiaxed microstructure prior

The plastic deformation of two classes of fine-grained aluminium alloys at elevated temperatures and slow strain rates have been investigated. One class of material, Al–Cu–Zr, was processed to develop banded microstructures; the other class, base

Grain growth and particle coarsening in Al–3.5Cu at a temperature of 450 °C has been studied. Plastic deformation of this Zener-pinned system at strain rates of 10 −3 and 10 −4 s −1 led to an increase in both the grain growth and particle co

Significant abnormal grain growth has been observed in an Al–3.5 wt.% Cu alloy at temperatures where the volume fraction of small CuAl 2 particles was less than about 0.01. The initial fine-grained material had a weak crystallographic texture and t

The paper discusses the role of stress on displacive phase transformations where plasticity is associated with variant selection, together with its implications for the resulting texture. In cases where the parent phase has a texture, the presence of

Al-0.1Mg with a 3μm grain size was deformed in channel die plane strain compression at temperatures up to 200oC. It was found that the reduction in grain thickness was significantly less than that predicted from geometric considerations, and at larg
