This ordered niobium carbide may be formulated as Nb_8C_7~′(NbC_(0.875)~′) which is formed by ordered omission of its C atoms. With the reciprocal lattice indexes or orientation relationship of transformation matrix between the ordered niobium carbide and α-Fe, the composite electron diffraction patterns can be conveniently indexed. 收稿日期: 1986-06-18      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 雍岐龙 郑鲁 孙珍宝 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I6/81 1 De Novion, C.H.; Lorenzelli, R.; Costa, P., C.
