快淬Nd-Fe-B永磁是80年代初期问世的,是国际上高科技产品。它是由美国GM公司研制发明的,目前国外只有少数实验开展快淬Nd-Fe-B永磁研究。我国快淬Nd-Fe-B永磁研究起始于1986年,为了加快快淬Nd-Fe-B永磁研究步伐,于1987年5月,上海市科委将该课题下达给上海钢研所和中科院上海冶金所联合研制,其主要研究内容包括:快淬Nd-Fe-B各向
Quenching Nd-Fe-B permanent magnet is the early 80’s came out, is an international high-tech products. It is developed by the United States GM company invented, at present only a few experiments abroad to carry out fast quenching Nd-Fe-B permanent magnet. China’s rapid quenching Nd-Fe-B permanent magnet study began in 1986, in order to speed up the quenching of Nd-Fe-B permanent magnet research pace, in May 1987, the Shanghai Science and Technology Commission to issue the issue to Shanghai Steel Research Institute And the Chinese Academy of Sciences Shanghai Institute of Metallurgy joint development, its main research include: quenching Nd-Fe-B each direction
