The composition of all samples was determined accurately by chemical analysis. It was found that the pseudo-ternary system Al-Mg_5Al_8-LaAl_4 is of the ternary eutectic type. There are three surfaces corresponding to the primary crystallization of a-Al, Mg_5Al_8 and LaAl_4 respectively, and three univariant lines related to the secondary crystallization. The temperature of the ternary eutectic, composed of 11.3 wt-% La, 62.9 wt-% Al and 25.8 wt-% Mg, was determined to be 445℃. 收稿日期: 1983-06-18      基金资助:南京工学院机械系金属材料研究室的资助 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 郑朝贵 邢娅 钱久信 叶于浦 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1983/V19/I6/61 1 Weibke, F.: Schmidt, W., Z.
