Abstract

The aim of this investigation is to study the effect of time and temperature on the solid-state diffusion welding of commercial aluminum alloy 2xxx series with a pure copper at 425°C, 475°C, 500°C, and 525°C during holding times from 15 min to 240 min. The main characterization techniques were optical microscopy, scanning electron microscopy, energy dispersive spectrometry, nanoindentation, microhardness measurements, and x-ray diffraction. Results showed that increasing the temperature and the holding time had an effect on the apparition of the intermetallics at the Al alloy/Cu interface. Five intermetallic phases namely Al2Cu, AlCu, Al3Cu4, Al2Cu3, and Al4Cu9 were identified at the interface. The mechanical properties of the welded joint Al/Cu alloy varied also with the time and temperature. The nanoindentation measurements showed that the highest values of hardness were recorded in AlCu and Al3Cu4 phases. The welding success of these dissimilar metals can be used for battery cables or to form heat exchanger plates for vehicles.

商用铝合金与纯铜的固态扩散焊

本研究的目的是研究时间和温度对商用铝合金2xxx系列与纯铜在425°C, 475°C, 500°C和525°C下保温15分钟至240分钟的固态扩散焊接的影响。主要表征技术有光学显微镜，扫描电子显微镜，能量色散光谱，纳米压痕，显微硬度测量和x射线衍射。结果表明，温度的升高和保温时间的延长对合金/Cu界面金属间化合物的形成有影响。在界面处鉴定出Al2Cu、AlCu、Al3Cu4、Al2Cu3和Al4Cu9五种金属间相。焊接接头Al/Cu合金的力学性能也随时间和温度的变化而变化。纳米压痕测量结果表明，AlCu和Al3Cu4相的硬度最高。这些不同金属的焊接成功可以用于电池电缆或形成车辆的热交换器板。
