Description
The effects of Si and Nb on the castabirity and the magnetic properties of Fe-Pt magnetic alloy were investigated.The surface roughness, magnetic properties, and the attractive forces were measured, and the following results were obtained.1.Addition of 0.1Si(mole%)or more improved the surface roughness and decreased casting defects.2.Addition of 0.2Si(mole%)or less or of 0.5Nb(mole%)or more produced excellent magnetic properties.Also, the addition of Si reduced the heat treatment time.3.Addition of 0.1Si(mole%)or less or of 0.6Nb(mole%)or more made alloys with strong attractive forces.4.The optimal composition was Fe-39.5Pt-0.65Nb-0.1Si(mole%)with regard to surface roughness, magnetic properties, and attractive forces.
