摘要 Slip deformation in Ti-6Al-4V titanium laser welds was observed. Laser welding was used to prepare the titanium welds. Macrostructure, microstructure, mechanical property and structure of laser welds were studied using optical microscope, scanning electron microscope, compression experiment, transmission electron microscope (TEM) and high resolution TEM. Subsequently, slip deformation mechanism occurred in fracture and etched weld was discussed. The results indicate that the maximum compression strength reaches 1.191 GPa. Slip deformation easily happens in titanium laser welds and the minimum slip bands are 600 nm and 75 nm respectively in fracture and etched laser welds. 观察Ti-6Al-4V钛合金焊缝的变形行为。采用激光焊方法制备焊缝,利用光学显微镜、扫描电镜、压缩力学试验、透射电镜及高分辨分析方法研究焊缝的宏观成形、微观组织、力学性能及结构。讨论了焊缝在压缩应力和腐蚀作用下的滑移变形机制。结果表明:钛合金激光焊缝的压缩强度最大可达1.191MPa;激光焊缝中可以观察到滑移行为,在断口中的滑移带最小为600nm,在腐蚀试样中发现的滑移带最小为75nm。
