Abstract

Ferrous soft magnetic materiais are required several efforts to realize high performance. 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 an effective technique to produce the high density and more complex shaped parts from Fe-Si hard metal powders.In this study, MIM process using several types of Fe-6.5 Si powders were performed, and their magnetic properties were investigated. Moreover, in order to improve the density and purity of injection molded compacts, the thermal debinding and sintering atmospheres were mainly investigated. The sintered compacts which have lower oxygen content showed high density and good soft magnetic properties.
