In our previous studies on the 4600 steels produced by metal injection molding (MIM) process using mixed elemental powders, the fine heterogeneous microstructure caused by the agglomeration of Ni powders was reported to be significantly effective for the improvement of mechanical properties. This study has been performed to obtain the high densified compacts using the bimodal powders the double pressing and sintering, and moreover to investigate the relationship between the mechanical properties and the heterogeneous microstructure of the compacts (4600 grade, 0.4 mass%C).
