Abstract The effects of ultrasonics on the process of solidification have been investiga(?)d in six pure metals (Zn, Cd, Sn, Pb, Sb, and Bi), a Pb-Sn (50%) eutectic alloy nd an Sb-Bi (10％) alloy. It has been found that:(1) ultrasonics reduce the cooling rate and lengthen the time of solidifi(?)tion;(2) ultrasonics reduce degree of supercooling;(3) ultrasonics refine the cast structure and the optimum power imput varies with metal.It is suggested that the change of cooling curve is due to the facs that:(1) the ultrasonic energy is converted into heat;(2) the atoms are compelled to vibrate in a direction para(?)el to the front of crystallization during freezing.
