摘要 进行了6 mm厚汽车新型钛合金Ti-6Al-4V-0.2Y板材的单面对接搅拌摩擦焊试验,并对接头的宏观形貌、X光无损探伤、显微组织、表面硬度和力学性能进行测试与分析。结果表明,钛合金Ti-6Al-4V-0.2Y板材的焊接接头成形好、表面光亮、无明显缺陷、力学性能较佳;接头的室温抗拉强度达到900 MPa、接头系数高达96%;接头硬度最大值位于焊核区、最小值位于前进侧热影响区。 Single-side friction stir butt welding tests for automotive titanium alloy Ti-6Al-4V-0.2Y plate with thickness of 6 mm were conducted,and the macroscopic morphology,X-ray nondestructive flaw detection,microstructure,surface hardness and mechanical properties of the joints were tested and analyzed in this paper.The results show that the joints have good shapes,bright surfaces,favorable mechanical properties and no obvious defects;tensile strength of the joint at room temperature reaches 900 MPa and the joint coefficient is up to 96%;the area with maximum and minimum hardness of weld joint is located in the weld nugget zone and the heat-affected zone of forward side,respectively.
