Summary

Glass encapsulated hot isostatic pressing of a 4 wt% Y233-Si3N4 was used to co-densify joined bodies with self-bonded and slip join interlayers. The resultant joins were of similar microstructure and mechanical behavior to the parent material. Joined materials were fabricated with mean 22° and 1300°C flexural strengths of 786.8 MPa and 713.6 MPa, respectively, without fracture originating in the joins. The joined materials survived 200 h at 1370°C under a 250 MPa constant flexural stress with a maximum strain of 0.006.
