1983年 11月日本住友特种金属公司在匹兹堡召开的国际磁学会议上,正式宣布研制成功一种新型钕铁硼永磁材料,并已将磁能积为35兆高奥的产品“Neomax”投入商业生产。与此同时,美国通用汽车公司也宣布采用快速淬冷法,制成钕铁硼磁体“Magnequench”。这一引人注目的成果,立即引起国际磁学界和商业界的极大重视。在一些报道和评论中,称此为“引起轰
November 1983 Japan Sumitomo Specialty Metals Corporation in Pittsburgh held an international conference on magnetic, officially announced the successful development of a new type of Nd-Fe-B permanent magnet materials, and has a product of magnetic energy product of 35 megaohoo “Neomax” into commercial produce. At the same time, General Motors Corp of the United States also announced the use of rapid quenching method, made of NdFeB magnets “Magnequench.” This remarkable achievement immediately aroused the great attention of the international magnetic and business communities. In some reports and comments, it is called "cause boom
