The A1_8B_4C_7, forming as liquid phase in the presence of additives B, C and Al at 1800-2100℃, may be coagulated at the grain boundaries among SiC particles. Because of an inferior wettability of the liquid phase A1_8B_4C_7 to SiC grains, the hot pressing may be significant to enhance its densification. 收稿日期: 1987-02-18      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 苏国跃 夏非 闻立时 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I2/237 1 猪股吉三,田中英彦,井上喜三郎,川端治雄,窯业协会誌,1980;88:353 2 Kingery W D, Bowon H K, Uhlmann D R.
