The tensile strength and the three‐point bending strength of Si 3 N 4 /Al/Invar joints were compared. The fracture modes in both tests were almost the same. Statistical treatments of the strengths showed that both strengths had a similar Weibull slope of ∼6. The three‐point bending strength was 2.5 times greater than the tensile strength. This magnification was slightly greater than that obtained from the relation of the effective areas in both tests.
