摘要

Power ultrasound was introduced to investigate its effects on the liquid phase separation and monotectic solidification process of ternary Al_62.6Sn_28.5Cu_8.9 immiscible alloy. As ultrasound power increases, the macrosegregation induced by liquid demixing is strikingly reduced. Meanwhile, a large number of spherical ternary (Al+Sn+θ(Al₂Cu)) monotectic cells are formed within ultrasonic field. Cavitation effect, which produces strong shockwaves and facilities the radial symmetry of temperature, concentration, and flow fields in front of liquid-solid interface accounts for these microstructure variations.
