Abstract: The fundamental rheological properties of metal injection molding (MIM) feedstock and binder are theoretically analysized. The viscosity of MIM binder and feedstock at different temperature and at different shear rate was measured and evaluated. The results indicated that MIM binder and feedstock possess pseudoplastic rheological behavior. The Fe Ni MIM feedstock prepared has the lower value of flow activation energy and the higher value of strain sensitivity exponent. Its injection and filling properties are good.
