Correlation of Processing, Microstructure and Superplasticity in an Al-MG-ZR Alloy
Abstract
Investigation of the influence of the strain history during thermomechanical processing of an A1-10Mg-0.1Zr was conducted. Refined, recrystallized microstructures resulted when larger strains were employed in the later passes of the TMP. Superplastic responses up to approximately 420 percent were obtained. Conversely, when smaller strains were at the later stages of the TMP, less recrystallized, coarser structures resulted, and the corresponding superplastic ductilities of approximately 280 percent were obtained.
