Abstract

Magnetic field forming is a promising method to produce high quality ferromagnetic materials. In this process, magnetic powder is formed in the high magnetic flux by the metal injection molding process. However the parameter of this process is very complicated and it is still difficult to obtain the optimum forming conditions. The analytical method is very effective tool to make such optimum forming design and to investigate the mechanism of the magnetic powder flow under applied magnetic field and pressing. We developed the coupling method of pressing load with magnetic field to simulate the magnetic field forming. In this method, granular modeling is utilized to simulate the mechanical behavior of the powder particles and the magnetic field is considered as a body force. In the numerical example, we analyzed the difference of the magnetic powder flow for pressing schedule and the preferred orientation of magnetizing of the magnetic powder is taken into account in the particle modeling.
