Mechanical Properties of Filler Metal in Si₃N₄/Austenitic Stainless Steel/Si₃N₄ Joints as Measured by Nanoindentation and its Relationship to the Interfacial Strength

Abstract:

Si3N4 specimens were joined in a high vacuum atmosphere under same experimental conditions using 50μm thick foils of three types of stainless steels (AISI 304, 316 and 321). The mechanical strength of these joints was evaluated by shear tests using a lap bond configuration and small but significant differences were found among them. Nanoindentation experiments were done on cross-sections of the bonded assemblies with a diamond Berkovich tip using an imposed penetration depth of 500 nm to reduce either surface effects or indentation size effect.
