Abstract
For miniaturization and complication of the shape of electronic devices in recent years, both high magnetic and mechanical properties are also being required to the soft magnetic components. A metal injection molding(MIM) process has the attributes of forming the high density, complex shaped and high performance components, which seems to be a suitables process for fabricating the higher performance soft magnetic components.<BR>In this paper, the effect of MIM process conditions on the magnetic and mechanical properties of soft magnetic materials such as Fe-Ni and Fe-Si alloys were investigated. Although the final density was obtained approximately 96% of theoretical in both steels, the magnetic properties were similar or inferior to that of the pure iron. Especially, the coercive force was increased with an addition of alloying elements, because the orientation of domain walls were prevented from the grain refining and the residual oxides. Generally, taking account of the improvement in the mechanical properties which are superior to that of the conventional P/M materials, it will be able to apply a MIM process to the soft magnetic components.
