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. 收稿日期: 1964-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 赵惠田 虞豪瑛 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1964/V7/I1/58 [1] #12 [2] #12 [3] #12 [4] #12 [5] #12 [6] #12 [7] Lane, D.
