| Abstract: | Through analysing residual stress after brazing carbon steel and Si_3N_4, the prin-ciple of selecting interlayer material for relaxing stress is discussed.Several kinds of practi-cable interlayer material are proposed from comparison of their thermal physical propertywith others. Also, by the brazing experiments , it is a good solution to the brazing flaw problem to use right joining type, with the increase fo the joint strength. |
