Abstract

In recent years, the soft magnetic material parts have been widely used in the fields of industrial equipments, consumer electronics, automobiles, and so on. To fabricate these soft magnetic material parts, electrical steel and P/M method is normaly used. With the increase of fabricating complex shaped parts, processing method with more flexibility in design also be needed. For this reason, MIM process is hoped to be a near-net-shape, cost reduction and mass production method which can fabricate three-dimensional complex shaped parts. Fe-Cr-based soft magnetic material is developed in 1960s∼1970s to be used in corrosive environments. Because it is less expensive than the PB permalloy. Mainly composition comprising a 13 %Cr or higher is used to make material stable. However, the maximum magnetic flux density of material decreases with increase of Cr content. In this research, the effect of Cr content on the magnetic properties under DC and AC magnetic field were investigated by mixing SUS430L alloy powder and iron powder.
