Resumen
In this study, AZ31 magnesium alloy and 6061 aluminum alloy were joined with Sn-xZn (x = 5, 10, 20 and 30 wt.%) fillers containing trace rare earth elements at 250 °C in air without the use of flux or a wetting layer. The bond shear strengths of AZ31 magnesium alloy/6061 aluminum alloy joints with Sn-5Zn-0.1RE, Sn-10Zn-0.1RE, Sn-20Zn-0.1RE, and Sn-30Zn-0.1RE fillers were determined to be 14.84, 17.08, 19.39 and 20.86 MPa, respectively. The shear strengths increased with increasing Zn content. The joint strengths of all four alloys significantly decreased with increasing aging time at 150 °C.
