搅拌摩擦焊接过程中的材料流动是获得良好接头的关键。然而，尽管有许多研究和许多模型，这种现象仍然没有完全理解。在这项研究中，物质流是三维可视化的x射线摄影使用一个微小的球形钨示踪剂。利用两对x射线透射实时成像系统观察了示踪剂在搅拌摩擦焊接过程中的运动。通过跟踪示踪剂的轨迹，获得了三维物质流。(C) 2011材料学报Elsevier Ltd.出版。版权所有。
Material flow during friction stir welding is crucial to obtaining sound joints. However, this phenomenon is still not fully understood despite many investigations and numerous models. In this study, the material flow is three-dimensionally visualized by X-ray radiography using a tiny spherical tungsten tracer. The movement of the tracer during the friction stir welding is observed by two pairs of X-ray transmission real-time imaging systems. The three-dimensional material flow is obtained by following the locus of the tracer. (C) 2011 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
