| 摘 要： | 铝、铜两种金属性能差异较大,用常规焊接方法难以实现连接,极大地限制了铝/铜复合接头的质量和应用范围.利用搅拌摩擦焊接技术成功焊接了防锈铝合金/紫铜异种金属的对接接头,通过焊缝接头表面宏观形貌观察、接头横断面组织分析及接头的抗拉强度分析母材相对位置对铝/铜搅拌摩擦焊接头性能的影响.结果表明,搅拌针相对配合面存在偏移的情况... |
| 关 键 词： | 搅拌摩擦焊 铝/铜异种金属 工艺优化 母材相对位置 |

| Abstract: | The dissimilar materials(5A06 aluminum alloy/copper T2) were difficultly welded by conventional fusion welding because of the enormous difference of their thermo-physical performances.The butt joint of dissimilar metals was welded with friction stir welding method.This paper mainly studied on the relative location effect of the base metal on the forming of the FSW joint by analyzing the mechanical properties,and the macro-morphology of weld surface and macrostructures of transverse section of welds.The resu... |
| Keywords: | friction stir welding Al/Cu dissimilar metals procedure optimization base metal relative location |
