Abstract

The mechanical properties at room and elevated temperatures of dispersion-strengthened-cast aluminum (DSC-Al) with high volume fractions of submicron Al2O3 oxide dispersoids were investigated. DSC-Al was reinforced with 25% Al2O3 to see whether it can exhibit high-strain-rate superplasticity near the solidus temperature. High temperature tensile tests were performed on DSC-Al at temperatures 14 K and 4 K below the solidus temperature and at strain rates between 7.4·10-3 s-1 and 2.5 s-1. While the room temperature ductility of DSC-Al is quite high, its formability at elevated temperatures is limited by its high creep strength and low creep ductility.
