| Abstract: | The superplasticity is a characteristic of high tensile elongation of materials withvery fine grain size under special conditions. The recent developments of superplastic ceramicsare introduced. The major requirements of superplasticity and characteristic nature ofsuperplastic ceramics are described. Meanwhile the factors affecting ceramic superplasticity arediscussed. Reference basis is provided for theoretical research and application in ceramicsuperplasticity. The studying way at present is indicated. |
