Hypereutectic Al
Si alloys were joined using Zn5Al filler metal at only 420 °C in air without flux.- •
Oxidation of hypereutectic Al
Si alloys at the liquid/solid interface was removed by ultrasound.- •
Si particulate-reinforced Zn
Al composites joints could be obtained by ultrasonic-assisted soldering.- •
The maximum strength of joints was ~ 108 MPa and then the fracture mainly occurred in the base metal.
