Effects of Laboratory Rolling Conditions on Continuously Cast AA5083

摘要

Quick Plastic Forming (QPF) is a recent adaptation of Superplastic Forming (SPE) 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.
