The change of saturation magnetization of the mixture powder was also measured. The results showed that Fe3N decomposed quickly with increasing milling time and disappeared after milling for 2 h, and some N atoms soluted in α-Fe. After milling for 24 h, a stable supersaturation solid solution was obtained. N content was about 0.290%-0.346%. With increasing milling time, the grain size decreased. After milling for 24 h, grain size reached a constant which is about 8 urn. The sites of N atoms nearby Fe atom changed during milling, so the saturation magnetization of the mixture powder initially decreased, but began to increase when milling time exceeded 5 h, and reached a constant when milling time exceeded 24 h. 收稿日期: 1998-01-18      基金资助:国家自然科学基金!59271013 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 徐晖 何开元 程力智 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1998/V34/I1/86 1 Suzuki S,Sakumoto H,Minegismi J,Omote V.IEEE Trans Magn,1981; 17: 3017 2 Kim T K,Takahashi M.Appl Phys Lett,1972;20:492 3 Nakajima K,Okamoto S.Appl Phys Lett,1990; 56(1): 92 4 魏玉年,孙克,冯远冰.姚玉书,刘世超,王文魁高压物理学报,1992;6(1):75(Wei Yunian, Sun Ke; Feng Yuanbing; Yao Yushu; Liu Shichao;Wang Wenkui.Chin J High PressPhys, 1992; 6(1): 75) 5 杉田,光同腾也 日本物理学会志,1992;47(9):728(Sugita Yasu,Teruoka Kariva.J Jpn Inst Phys,1992; 47(9): 728) 6 Huang M Q;Wallace W E,Simizu S,Pedziwiatr A T,Obermyer R T,Sankar S G J Appl Phys, 199475:6574 7 Koyano T,Takizawa T.Jpn J Appl Phys,1993;32:L1524 8 Wriedt H A,Zwell L.Trans Metall AIME,1962 224:1242 9 Collette G,Roederer C;Crussard C.Mem Sci Rev Met,1961; 58(1):61 10 范雄,X射线金属学.北京:机械工业出版社,1981:150(Fan Xiong.X-ray Metallurgy.Beijing:Mechanical Industry Press,1981:150)N No related articles found!
