The rheological by M. Khakbiz, A. Simchi and R. Bagher for Investigation of rheological behaviour of 316L stainless steel–3 wt-%TiC powder injection moulding. It was found that all the feedstocks are basically pseudoplastic but the values of flow behaviour index n are influenced by the TiC addition, the results show that TiC addition plays an important role in rheological parameters, i.e. TiC particles decrease the viscosity of PIM feedstock and this effect is more pronounced in the system comprising higher solid volume fraction. From the viewpoint of mouldability, the optimum PIM condition for the SS/TiC composite powder containing a wax based binder system was found at 55% solid volume fraction and 70°C. At this condition, the viscosity of feedstock is low enough to fulfill the requirements of a medium pressure, injection moulding process.
