It was found that the carbon-boride Fe_(23)(C, B)_6 precipitates out along the austenitic grain boundary of solid solution treatment specimen after water cooled even in iced salt water. The Fe_(23)(C, B)_6 appears an acid soluble thin plate on rapid cooling. At the cooling rate up to 20℃/s, the precipitate is further presented in the interior of the grain. Both intergranular and intragranular ones may quickly grow up by isothermal treatment at 750℃. While the isothermal treating temperature raised to 850℃, the boride, to form BN instead, precipitates out around the spherical MnS grain as nucleus of crystallization to obtain a compound of MnS+BN. 收稿日期: 1982-05-18      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 尹士科 小松肇 谷野满 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1982/V18/I5/559 1 镰田仁,最新铁纲状熊分析,株式会社,东京,1979 p.277． 2 黑沢文夫;田口勇;松本能太郎,日本金属学会誌,43(1979) ,1068． 3 渡辺征一;大谷泰夫;邦武立郎,铁钢,62(1976) ,1842． 4 竹田元彦;吉岡啓一;小野宽;大橋延夫,铁钢,63(1977) ,622． No related articles found!
