概要

• 論文の詳細を見る

• Joining of aluminum to the 304-type stainless steel was performed at 673K for different ultrasonic application times. Different reaction layers could be observed at the interface, containing Fe-Al, Fe-Zn, and Fe-Al solid solutions. The maximum bond strength of 146MPa was obtained for Al/304 joint brazed at 673K for 3 seconds UAT. A critical remained thickness of the filler alloy after ultrasonic application is believed to improve the interfacial joining. Extending the ultrasonic application time beyond 3 seconds causes a bulk escape of the brazing alloy from the interface which decreases the bond strength.
