| Outline of Final Research Achievements |
Friction stir welding of aluminum alloy and steel is attractive method to fabricate light structure for transportation vehicle. The welding conditions, such as heat input (tool rotation speed and welding speed) and shape of welding tool shape and weld line influence on the weld material and the material flow during welding. Control of material flow is important for fabrication of sound weld without defect. Thus, the material flow in the weld was investigated by using X-ray CT technique after welding and numerical simulation. Also, stability of reaction layer in the weld interface by this material flow was evaluated by strength measurement and X-ray diffraction by synchrotron light.
