Ｆｅ基和Ｃｏ基非晶合金具有优越的软磁特性 ,已广泛用在电源器件、磁头和各种传感器等方面。为了更加广泛地利用这种材料 ,当前人们正在积极研究利用粉末冶金法等制作块体非晶材料的可能性 ,但因非晶粉末的变形能太小以致难以获取具有良好软磁性的块体材料。近年来发现Ｍｇ基? Fe-based and Co-based amorphous alloys with superior soft magnetic properties have been widely used in power devices, heads and various sensors. In order to utilize this material more widely, people are actively studying the possibility of making a bulk amorphous material by the powder metallurgy method or the like, but because the deformation energy of the amorphous powder is so small that it is difficult to obtain a bulk material having good soft magnetic properties . In recent years found that Mg-based?
