It was found that the dendrites grow preferentially along <100> directions and the crystalline steps belong mainly to {100} and {110} planes.In the neighbourhood of the unhealed porosities the alloy matrix appeared to be embrittled and in certain cases cleavage fracture was observed. 收稿日期: 1978-03-18      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 周敬 常昕 郭可信 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1978/V14/I3/246 [1] Ryder, D.
