| 中文摘要: |
| 搅拌摩擦焊是目前钛合金焊接技术研究的热点。从搅拌头材料与结构设计、焊接工艺与组织性能关系、焊接过程数值仿真等方面综述了钛合金搅拌摩擦焊国内外研究现状。以现有的研究结果来看，搅拌摩擦焊是实现钛合金高强可靠连接的有效途径，选择合适的焊接参数和焊后热处理工艺可获得高质量钛合金焊接接头;但由于对钛合金用高温高强高耐磨搅拌头研制不足，以及对焊接过程多物理场表征技术、数值仿真、辅助焊接工艺等研究较少，限制了其研究进展和应用。 |
| 英文摘要: |
| Friction stir welding (FSW) has become a research hot spot of titanium alloy welding technology. In this paper, the research status of FSW of titanium alloy at home and abroad is reviewed from the aspects of materials and structures design of FSW tool, relationships between process and microstructure and properties, numerical simulation of welding process, etc. According to the existing research results, FSW is an effective way to realize the high strength and reliable connection of titanium alloy. Selecting appropriate welding parameters and post weld heat treatment process can obtain high-quality titanium alloy welded joints; however, due to the lack of research and development of high temperature, high strength and high wear resistance FSW tool for titanium alloy, as well as the lack of research on multi-physical field characterization technology, numerical simulation and auxiliary welding process, its research progress and application are limited. |
