Nd-Fe-B永磁是一种新型的永磁材料,自从日本人M.Sagawa等人研制出来以后,引起了世界磁学界及工业界的极大关注,由于它具有极为优异的磁性能,因此各国都相继进行研究。美国学者K.S.V.L. Narasimhan等人研制的磁体最大磁能积已达到(BH)_m=44.8MGOe。 我院从1983年10月开始进行Nd-Fe-B磁体的研制工作。1986年磁性能已达到(BH)_m=44.5MGOe,接近国际先进的实验室水平。并且在电子水表,转速测量表,测振仪传感器,扬声器,等方面获得广泛应用,今后还将开发在电机上应用的领域。 我院精密合金教研室系统地研究了合金成分、工艺制度和磁性的关系,研究结果表
Nd-Fe-B permanent magnet is a new type of permanent magnet material. Since the Japanese M.Sagawa et al. Developed it, it has aroused great attention of the world’s magnetism industry and industry. Due to its excellent magnetic properties, Therefore, all countries have conducted research. American scholar K.S.V.L. Narasimhan, who developed the maximum magnet energy product has reached (BH) _m = 44.8MGOe. Our hospital from October 1983 for the development of Nd-Fe-B magnet work. Magnetic properties in 1986 has reached (BH) _m = 44.5MGOe, close to the international advanced laboratory level. And in the electronic water meter, speed measurement table, vibrometer sensor, speaker, etc. has been widely used in the future will also develop the field of application of the motor. Precision Alloy Teaching and Research Institute of our hospital systematically studied the composition of alloys, the relationship between the system and the magnetism, the results table
