| Abstract: |
| Abstract Relationship graph of preheating temperature - diluent arnount adiabatci temperature is drawn. Changes of strain of exterior surface of the composite pipe is measured after the removal of ceramic and transition layer. Thus .State of residual stress distribution of each layer is deduced, and values of residual stress between transition layer and ceramic layer and of the interior ceramic layer are estimated. |
