It is found that the characteristic acoustic emission is dependent on the material nature, the alloy composition and the solidification process. The acoustic emission technique is applicable to determine the phase diagram of the Sn-Bi binary system and to monitor the solidification processing. Thus, it seems that this technique may be available means to theoretically and technologically study the dynamical micro-mechanism of the solidification of metal and alloy as well as of the casting process. 收稿日期: 1984-03-18      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 纪士辰 朱祖铭 王国志 李英敖 胡壮麒 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I3/237 1 Kaiser, J., Arch Eisenhuettenwes., 24 (1953) , 43． 2 Chalmers, B., Principles of Solidification, Wiley, New York, 1964, p. 124． 3 Hansen, M., Constitutions of Binary Alloys, McGraw-Hill, New York, 1958, p. 337． 4 Chalmers, B., Principles of Solidification, Wiley, New York, 1964, p. 41, 123． No related articles found!
