This paper introduced a method of rapid solid-phase bonding Al block with Ag as the intermediate layer by longitudinalultrasonic vibration under eutectic temperature in the atmospheric environment. This method is suitable for the application ofstructural lightweight design. It was observed that Al and Ag difuse with each other in the weld seam to form an intermetallic compound Ag2Al with close hexagonal structure. The efects of diferent reaction temperatures and ultrasonic vibrationtimes on the microstructure and mechanical properties of intermetallic compound Ag2Al were discussed. The infuence ofthe efect of ultrasonic softening waves on surface oxide flm rupture and element difusion was explored. With the increaseof ultrasonic vibration time, the intermetallic compounds grew along with the interface and the thickness increased. Whenthe welding temperature was 500 °C and the ultrasonic vibration was 20 s, the highest average strength of the welded jointreaches 46.68 MPa.
