| 中文摘要: |
| 搅拌摩擦焊是一种新型的固相焊接技术,目前国内外的研究主要集中在工艺、组织、力学性能等方面,而有关搅拌摩擦焊缝内部残余应力的研究相对较少。 由于检测设备的限制,国内主要采用有损检测方法,无损检测方法却很少。 详细综述了国内有关搅拌摩擦焊件内部残余应力测试的钻孔法、云纹干涉法,以及国内外无损检测方法中的 X 射线衍射法、中子衍射法和高能同步辐射法的研究概况,讨论了各种检测方法的优缺点,对未来搅拌摩擦焊残余应力的研究作了展望。 |
| 英文摘要: |
| Friction stir welding is a new solid-state welding technology. At present, studies of domestic and overseas focus on processes, microstructure and mechanical properties. Studies on the initial residual stress of friction stir welding are relative fewer. Because of the limited testing equipment, the destructive tests are usually adopted by domestic researchers, but the non-destructive tests are so fewer. The destructive, such as hole-drilling and moire interferometry, and non-destructive tests, such as X-ray diffraction, neutron diffraction and synchrotron radiation, are summarized in detail. Mean-while, the advantages and disadvantages of the detection methods are discussed and a prospection for the study of friction stir welding residual stress is made. |
