Magnesium (Mg) matrix composites has a great potential to apply to automobile, aerospace industries since the density of magnesium is low as compared with other metal alloys and the composite is expected to achieve excellent mechanical, physical and thermal properties. High Strain Rate Superplasticity (HSRS) is expected to offer the efficiently near-net shape forming method for magnesium matrix composites, since HSRS materials usually exhibit an elongation of 250--600% at a high strain rate of about 0.1--10s{sup {minus}1}. The purpose of this study is to reveal the HSRS in a AlN particulate reinforced Mg-5wt%Al alloy composite fabricated by a vortex method. In addition, the superplastic deformation mechanism of the Mg matrix composite will be discussed.
