一、引言北京冶金试验厂与北京钢铁学院于1971年初,接受了一项研制磁能积超过11.0×10~6高斯·奥斯特的铝镍钴磁钢的国家压务。据了解,目前在生产水平较高的日本,其典型产品NKS—10的最高磁能积(BH)_(max)约为8.6—11×10~6高·奥。据报导,荷兰在实
I. INTRODUCTION Beijing Metallurgical Experimental Plant and Beijing Iron and Steel Institute accepted the national repression of alnico magnets with a magnetic energy product exceeding 11.0 × 10 -6 Gauss Oster in early 1971. It is understood that at present a high level of production in Japan, the typical product NKS-10 maximum energy product (BH) _ (max) is about 8.6-11 × 10 ~ 6 high · Austria. It is reported that the Netherlands is in fact
