Summary

Joined ceramic/intermetallic materials were synthesized by the self-propagating high-temperature synthesis process. The materials joined were Tic and NiAl, while the joint layer was a functionally gradient material layer consisting of TiC/NiAl in a prespecified spatial composition gradient. Microstructural analysis showed that nearly complete densification was achieved and that the composition gradient was retained following the fabrication process. In addition, design calculations were performed for joined ceramic/metal composites. The first portion of the calculations dealt with the TiC/NiAl material system and illustrated the importance of sample geometry parameters on the development of thermal stresses. The second portion focused on the influence of key material property parameters on transient thermal stresses for fixed sample geometry.
