It shows that Sm content is about 27 wt%, instead of 25.5 wt% reported by Ojima. It is shown that the liguid phase sintering process, quite other than a simple solid phase sintering, is favourable to control and to adjust exactly their compositions, to play fully the active role in step aging treatment, to enhance strongly the coercivity and the energy product and to prepare successfully magnets with excellent properties. The highest valuc of energy product, 30.5 MGs·Oe, has been obtained. 收稿日期: 1981-04-18      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 肖文涛 祝景汉 孙天铎 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I4/424 [1] Ojima, T., et al., IEEE Trans.
