| Abstract: | Based on obtaining superplasticity of 20 steel,its cavities and fracture behavior was researched.By observing the production of cavities and measuring the growth of cavities,a model explaining the formation of cavity nucleus in superplastic material was given out.The results show that the fracture of superplastic 20 steel includes 2 kinds of fracture types:the fracture along crystal and through crystall. |
