An A1N particulate reinforced aluminum alloy composite exhibits a high elastic modulus and a high thermal conductivity. Moreover, its thermal expansion is similar to silicon so that this composite is expected to apply to semi-conductor packaging in the aerospace structure. In addition, it was also found that the composite could produce superplasticity at high strain rates. But the superplastic characteristics of the aluminum alloy composites has not yet been clear entirely. The purpose of this study is to develop a thermomechanical processing route to produce a fine microstructure and to further produce HSRS in a 1N90 pure aluminum and in a A1N particulate reinforced 1N90 pure aluminum composite. In addition, the superplastic characteristics of the composite and the pure aluminum will also be discussed.
