摘要

Ultrarapid formation of hypereutectic Al-Si alloys /Sn-51In/ hypereutectic Al-Si alloys joints was achieved within 0.2 s via an ultrasound-induced liquid phase method at 180 ℃ in air. Ultrasonic vibration accelerated the element inter-diffusion between aluminium and indium to induce liquid phase. The joints consisted of Si particles, an Al-In solid solution and intermetallic compounds. The migration behaviour of Si particles, which were regarded as tracers, under the influence of ultrasonic vibration was used to investigate the joint formation. As the ultrasonic vibration time increased, the shear strength of the joints increased. The existence of Sn in the interlayer considerably affected the joint shear strength by forming intermetallic compounds.
