中文摘要：

利用铜模吸铸法制备了Fe63-xNd37Alx(x=5,8,10,12)合金,采用示差扫描量热法(DSC)、振动样品磁强计(VSM)和扫描电子显微镜(SEM)研究了其磁性能.结果表明:Fe63-xNd37Alx(x=5,8,10,12)合金均表现为软磁性.铸态Fe53Nd37Al10合金由非晶相Nd59Fe28Al13和晶态相Fe75Nd18Al7组成,其中的非晶相Nd59Fe28Al13在合金中表现为软磁性,但相同成分的利用铜模吸铸法制备的大块非晶合金却表现为硬磁性,这是由于Fe53Nd37Al10合金中的非晶相投有短程有序的团簇存在的缘故.

英文摘要：

The magnetic properties of the Fe63-xNd37Alx(x = 5, 8, 10, 12) alloys made by suction casting into the copper mold were investigated by differential scanning calorimetry (DSC), vibrating sample magnetometer (VSM), and the scanning electron microscope (SEM). The results show that the Fe63-xNd37Alx (x= 5, 8, 10, 12) alloys all show soft magnetic behavior. The as- cast Fe53Nd37Al10 alloy is composed of amorphous phase (Nd59Fe28Al13) and crystalline phase (Fe75Nd18Al7). The amorphous phase in the alloy shows so...
