| Outline of Final Research Achievements |
A new welding method by rubbing the materials without using the rotating tool has been developed by succeeding in suppressing the temperature rise of the material at the vicinity of the interface, that is, suppressing the decrease in strength of the material. By performing joining without transformation, a finely recrystallized structure was obtained at the interface, and a joint having 100% joint efficiency was successfully obtained. In addition to the friction welding, a linear driven friction welding system was constructed to expand the scope of application.
