High strain rate superplasticity (HSRS) in ceramic whisker or particulate reinforced aluminum alloy composites is expected to offer an efficiently near-net shape forming technique for automobile, aerospace, and even semi-conductor industries, because the HSRS materials usually exhibit lower flow stress and higher total elongation of 250--600% at a high strain rate such as 0.1 {approximately} 10 s{sup {minus}1}. The purpose of this study is to make clear an effect of hot rolling after extrusion and squeeze casting to HSRS behavior of a SiC particulate reinforced aluminum alloy composite fabricated by a vortex method. In addition, the deformation mechanism of the HSRS in the composite will also be discussed.
