一、前言 铁基超微晶材料自88年底问世以来,经短暂的材质、制作工艺模索,很快地转入应用研究,由于新材料具有很高的μ_i很低的高频损耗及高饱和磁感应,深受电子器件设计人员的青睐,取代坡莫合金(高μ_i)、薄硅钢(高B低Pc)及铁氧体(高频低Pc)等小型电子器件铁芯,成效显著。1990年底,上海钢研所与西安电力机械制造公司(西电)签订协
First, the foreword Since the advent of iron-based nanocrystalline materials since the end of 88, after a short period of material, production process modeling, quickly into the application of research, due to the new material has a very high μ_i high frequency loss and high saturation magnetic induction , Which is favored by electronic device designers. It has achieved remarkable results in replacing small electronic devices such as permalloy (high μ_i), thin silicon steel (high B low Pc) and ferrite (high frequency low low Pc). By the end of 1990, Shanghai Steel Research Institute and Xi’an Electric Machinery Manufacturing Company (West) signed an association
