研究了1060铝合金与工业纯铜的搅拌摩擦焊接的显微组织和力学性能。通过在750 ~ 1500 rpm和30 ~ 375 mm/min范围内调节转速和焊接速度，获得了最佳力学性能。在搅拌区观察到各种不同形态和性能的显微组织。结果表明，Al4Cu9、AlCu和Al2Cu是界面区形成的主要金属间化合物。讨论了接头界面硬脆金属间相的形成对接头抗剪强度的影响。(C) 2007 Elsevier B.V.版权所有
This paper focuses on the microstructural and mechanical properties of the friction stir welding (FSW) of 1060 aluminum alloy to a commercially pure copper. A number of FSW experiments were carried out to obtain the optimum mechanical properties by adjusting the rotational speed and welding speed in the range of 750-1500 rpm and 30-375 mm/min, respectively. Various microstructures with different morphologies and properties were observed in the stir zone. The results indicated that Al4Cu9, AlCu and Al2Cu are the main intermetallic compounds formed in the interfacial region. The effect of formation of hard and brittle intermetallic phase at the interface of the joints on the shear strength of the joint is discussed. (C) 2007 Elsevier B.V. All rights reserved.
