Abstract:

A study is being made on the nature of stress distribution in the brazed joint and the mechanism of joint failure. The tensile deformation of a prototype composite material, the brazed joint, was measured. Highly localized non-uniform straining in the axial direction was observed. Cleavage facets were detected on fracture surfaces in the case of silver filler and void formation in the case of lead filler, using mild steel as the base material. These voids, as indicated in microradiographs, are elongated and have a preferred orientation within an individual grain it is suspected that the X-ray indications are of voids which originated in small patches of brittle fracture and opened up by plastic deformation, rather than of voids which nucleated and grew entirely by plastic deformation.
