| titleOfInvention | Characterization method of residual stress of ceramic/metal heterogeneous soldered joint |
| abstract | The invention provides a characterization method of residual stress of a ceramic/metal heterogeneous brazed joint, which comprises the following steps: s1, collecting connection parameters of the braze welding joint to be characterized; s2, selecting ceramic eta which is homogeneous with the ceramic base material of the soldered joint to be characterized, cutting and polishing to obtain the ceramic eta to be diffusion-connected; s3, assembling the ceramic eta to be diffusion-connected and the metal sheet to form a connection component to be diffused; s4, cutting the connecting component to be diffused to form a stress characterization piece, replacing a ceramic base material with the stress characterization piece, and performing brazing connection according to the connection parameters in the step S1 to obtain a simulated connecting component; and S5, cutting the simulation connecting assembly to obtain a test piece, and testing the bending degree of the stress characterization piece contained on the test piece. The invention prepares the test piece which is completely the same as the process condition of the soldering heterogeneous joint to be characterized and the microstructure of the welding line, and utilizes the bending degree of the stress characterization piece to characterize the magnitude of the residual stress, and the characterization method is simple and easy to implement and has high measurement accuracy. |
