High strain rate superplasticity (HSRS) for a ceramic whisker or particulate reinforced aluminum alloy composites exhibiting a total elongation of 250--600% at a high strain rate such as 0.1--10S[sup [minus]1] is expected to establish an efficient, near-net shape forming for automobile engineering components, aerospace structures and semi-conductor packagings. The purpose of this study is to establish thermomechanical processing to build fine microstructure and to produce HSRS for a SiC particulate reinforced aluminum alloy composite fabricated by a voltex method and to make clear the superplastic characteristics.
