Abstract:Ultrasonic treatment of the melt metals is a hot research topic. In this paper, ultrasound was introduced from the bottom into liquid metal. By this way, the ultrasonic treatment can be acted on the liquid metal from pouring to the end of solidification. The effect of ultrasonic treatment on the microstructure of Sn-58wt.%Bi alloy are studied with the variation of different power levels. The microstructure of the treated specimen are significantly refined and only granular bismuth and tin phases is obtained, c… Show more
