Abstract

Ferrous soft magnetic materials are required several efforts to realize high performance magnetic properties. In powder metallurgy processing, both high density and high purity are necessary to obtain the excellent soft magnetic properties. Metal injection molding (MIM) process is hoped to be an effective technique to produce the high density and more complex shaped parts from Fe-Si hard metal powders. In this study, Fe-6.5Si sintered compacts were produced by MIM process using elemental powders and their magnetic properties were investigated. The oxygen contents of sintered compacts were strongly influenced by the original powder, and the lower oxygen content powder showed high density and good soft magnetic properties.
