<p>Quick Plastic Forming (QPF) is a recent adaptation of Superplastic Forming  (SPF) that allows economical fabrication of complex components using superplastic  material. QPF requires refined, equiaxed grains and high-angle grain boundaries in the  microstructure to enhance sheet deformation by GBS at the high strain rates involved.  This study evaluates the effects of laboratory rolling conditions on continuously cast  AA5083 in the hot-band condition in anticipation of QPF. Orientation imaging  microscopy, scanning electron microscopy and X-ray analysis were used to analyze roles  of the geometric dynamic recrystallization and particle stimulated nucleation of  recrystallization in the microstructure evolution during rolling. A refined microstructure  was developed during the rolling procedures but mechanical property data indicated low  to moderate ductility and failure by excessive cavity formation. Factors influencing the  development of microstructure and mechanical properties during laboratory rolling were  investigated.
