摘要：

Material flow is a key phenomenon to obtain sound joints by FSW, and it is affected by the welded material. However, the material flow during FSW has not been totally clarified. It seems to be difficult to understand the material flow by the tracer method or observation of the microstructure in the stir zone. Therefore, in this study, the material flows of steel and aluminum were three-dimensionally visualized by X-ray radiography using a tiny spherical tungsten tracer. The movement of the tracer during the friction stir welding was observed by two pairs of x-ray transmission real-time imaging systems. The three-dimensional material flow is also obtained by observing locus of the tracer. The result revealed the effect of the welded material on the material flow.
