The following nonmetallic inclusions have been identified: MoO_2, γ-Mo_2N, Mo_2C, ZrO_2, ZrN, TiO, TiN, TiO_2 (containing Mo), α-Al_2O_3 and SiO_2. It was found that no MoO_2 was observed at the grain boundaries even at 2000 X when the oxygen content in molybdenum is below 0.0027%. 收稿日期: 1966-02-18      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 朱惠滋 李静媛 浦以健 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1966/V9/I2/189 [1] Parke, R.
