Abstract
Experimental data are presented on the influence of component yield strength and joint geometry on the mechanical behavior of transverse brazed joints. The systems studied were various iron alloys brazed with dilute silver alloys. From these data a model is developed for the deformation and ductile failure of brazed joints. In thick and thin joints, macroscopic plastic instability and hydrostatic tension respectively are the major causes of void growth and ductile fracture. Strain hardening in the braze metal is found to be an important factor in delaying fracture in both cases. Increases in the braze metal yield strength are accompanied by increases in the tensile strength of a brazed joint if the yield strength of the base metal exceeds the fracture strength of the joint. The loss of stress triaxiality which accompanies base metal yielding severely limits joint strength.
