An innovative approach to joining metals to ceramics
- Univ. of Arizona, Tucson, AZ (United States); and others
In contrast to most conventional approaches in modeling metal-ceramic couples, in the present investigation, the elastic behavior of the ceramic was modeled with a limit defined by the Drucker-Prager model. The resulting model affords excellent qualitative and quantitative ability to predict cracking in the ceramic component, if any, during the post-brazing cool-down stage. Several plane-stress geometries were investigated, and the numerical predictions compared with experimental results. In each and every case, the model successfully predicted cracking in the ceramic component, as well as predicted the crack initiation site which compared favorably with experimental observations. This model was successfully utilized in the design of a crack-free joint between Ceralloy 147-3 Si{sub 3}N{sub 4} and 1040 Steel without using soft metals as interlayers.
