Abstract : During the SBIR Phase II study, we have applied Dynamic Magnetic Compaction (DMC) technology for compacting the steel powders to high densities of 7.6 gms/cc. The conventional die pressing will yield densities of ^ 7.2 gms/cc in steel powders. Auto market, requires new methods to produce high density (> 7.5 gms/cc) pans in a cost effective manner. Currently, the wrought or forged material is machined into a given shape and thus the part cost is high. We have shown the potential of the DMC technology to manufacture high density net shape steel parts such as the cylinders, rings, and parts with internal features. During the Phase II project we have initiated the DMC process study through the compaction and modelling. Towards the end of SBIR Phase II project, IAP Research, Inc., was awarded an Applied Technology Program (ATP) award of $8.7M for three years with General Motors and Zenith Sintered Product, Inc. (auto P/M part producer) as joint venture partners to continue the study on DMC process and bring the technology to the preproduction stage.
