High nitrogen austenitic stainless steel was prepared by metal injection molding,and the effect of viscosity of feedstock consisted of paraffin wax(PW),high density polyethylene(HDPE),polypylene(PP)and aric acid(SA),as well as shear rate and temperature on the viscosity was investigated.And the influence of polymer components on the rheological behavior of feedstock was also compared.The results showed that the feedstock exhibited better rheological properties when the binder was made of 65%PW,30%HDPE and 5%SA,which is more suitable as the organic vehicle for MIM of high nitrogen austenitic.
