The charpy V-nocth impact characteristics of friction welded joints have been studied with attention to the influences of testing temperature, solution treatment and base metal characteristics. The results are summarized as follows. (1) The ductile brittle transition of friction welded joints from -196℃ to 20℃ was not observed. (2) The main cause of the decrease in the charpy absorbed energy of the friction welded joint was considered to be the reorientation of the non-metallic inclusions contained in the base metal. (3) Solution treatment at 1050℃ of charpy absorbed energy of friction welded joint gave at most 55% value of that of the base metal, remainning the fiber structure present on the fracture surface. (4) Charpy V-notch impact characteristics of base metal was considered to be transmitted to those of the friction welded joint.
