Abstract
Al/Fe clad materials joining with Al alloy were successfully realized at intermediate temperature without flux in air by using ultrasonic-assisted brazing. Mechanical properties and microstructure of joints with Zn-Al and Al-Si filler metals were studied. The experiment showed that the oxide film of Al film at clad materials were effectively removed when Al/Fe clad materials were brazed with 5A06 alloy by using Zn-Al filler metal. Diffusion of Al film was easily controlled. There were not Fe-Al intermetallic compounds in the joins. Shear strength of joints was higher than 70 MPa when the Al film was not completely dissolved. The joints were composed of α-Al, η-Zn, Zn-Al eutectic and Zn-Al eutectoid. When Al/Fe clad materials were brazed with 1100 Al by using Al-Si filler metal, the Al film was completely dissolved in a short time. Fe-Al-Si intermetallic compounds and microcracks were observed and the shear strength was only 20 MPa.
