Instrumented Charpy impact tests and slow-bend Chaxpy tests of diflusion bonded joints were performed to clarify the cause of low absorbed energy of the joints. Elasto-plastic analyses were also carried out in order to study the deformation behavior of the tensile and V notched specimens for joints. As the results, the fracture behaviors under the impact and static loads related to V notched specimen were almost the same. The degradation of Charpy strength of joints caused by the mechanical heterogeneity of both metals near bonded zone.
