The experimental verification was made of the Al-Cu alloy by the authers and of the previous data collected. 收稿日期: 1986-04-18      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 张承甫 肖理明 刘瑞祥 李胜 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I4/138 1 Flemings, M.C., Solidification Processing, McGraw-Hill, New York, 1974, p. 83． 2 椙山正孝;梅田高照;加藤宽,日本金属学会誌,38(1974) ,1． 3 MacCartney, D.G.; Hunt, J.D., Acta Metall., 29 (1981) , 1851.
