Abstract: | In this research, Al 3003/Zn sheets with different Zn layer thicknesses (as filler layer) have been soldered to the monolithic Al 3003 sheets. The effects of Zn layer thickness and soldering time at the peak temperature on the joint strength of soldered Al 3003 alloy by pure Zn filler (as the soldering sheets) have been evaluated. Furthermore, microstructure and fracture mechanism of Al 3003/Zn/Al 3003 soldered joints have been studied. The results indicate that by decreasing the Zn layer thickness and increasing the holding time at the peak temperature of soldering, the joint strength improves. Additionally, microscope examinations show that the fracture type of the Al 3003/Zn/Al 3003 soldered joint is predominantly brittle. |
