摘要：
Superplastic aluminium alloys and their forming are reviewed. General characteristics of superplasticity and its evaluation are briefly summarized and the grain refining methods of materials to obtain superplasticity are explained according to J. A. Wert. Especially, it is emphasized that the mechanism of grain refinement in the high strength aluminium alloys is developed by the investigation of intermediate thermomechanical treatment. The recent studies of superplasticity and forming in 7475, Al-Li alloys (8090, 2090), P/M alloys and Metal Matrix Composites are described.
