Abstract

The experiments were carried out in order to examine the relationship between shear, tension, three-point and four-point bending strengths of Si3N4/Inconel 600 alloy joints. Average values of the shear, tension, and three and four point bending strengths were 178, 233, 321, and 344 MPa, respectively. From the results the strength ratio was 1 : 1.32 : 1.81 : 1.95 in the order of shear, tension, three-point and four-point bend tests. Based on Weibull moduli three-point bend and tension tests showed smaller strength scattering than did the shear and four-point bend tests. As opposed to the behaviour observed for the monolithic ceramic, the average bending strength of Si3N4/Inconel 600 alloy joints decreased as the effective volume of the bend test specimen increased.
