In recent years, there have been a lot of research efforts in studying high-strain-rate superplasticity of aluminum matrix composites. However, the superplastic deformation behavior of the composites has not been fully understood. Superplastic deformation mechanism in aluminum matrix composites was considered to be grain boundary sliding and interfacial sliding. In this paper, the model proposed recently by the authors to explain the superplastic deformation of a particulate reinforced aluminium matrix composite at temperatures above and below its solidus temperatures is further developed. The theoretical predictions are in agreement with the published experimental findings.
