Cavitation damage is commonly observed in superplastic materials,and leads to a substantial deterioration in the me-chanical properties of post -superplastically deformed components or reducing the superplastic formability. In the paper,the current understanding of this phenomenon is reviewed. The theoretical models of cavitation unclei, growth;and interlinkage are briefly inrtoduced, and compared with experimental data. Finally,the influence of hydrostatic pressure and electric field on cavitation is discu...
