The results confirmed that the <0001> direction of graphite crystal is perpendicular to the "annual ring" lines revealed by ion bombardment. Each cone in a nodular graphite is composed of many microcrystallites with a small angle each other in their orientations. The morie patterns in the TEM picture of the graphite were also analysed. It is considered that they result from some structure defects such as twins existing in the graphite. 收稿日期: 1987-06-18      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 宋维锡 杨文英 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I6/594 1 Pan E N, Ogi K, Loper C R Jr. Trans Am Foundrymen's Soc, 1982; 90: 509 2 张维德,朱振华,潘振华,徐治岩,上海工业大学学报,1981;(4) :60 3 赵西成.北京钢铁学院硕士学位论文.1983 4 Su J Y, Chow C T, Wallace J F.
