Investigation of Manufacturability of WC Particle Reinforced Steels by Powder Metallurgy Method

Abstract

Stainless steels are the development of low-alloyed or unalloyed steels. Stainless steels arewidely used in industry and biomaterial fields due to their advanced properties such as superior mechanicalproperties, resistance to corrosion, and use as a biomaterial. Graphite, iron, titanium, vanadium and tungstencarbide were used in this study. By PM method, 0.05 wt% and 0.1% WC were added into graphite, ironand titanium powders. The powders were subjected to mechanical alloying process with a mechanicalalloying device at 400 rpm for 60 minutes. Samples of each composition were formed by cold pressing themixed powders with a one-way press device under 600 MPa pressure in the mold produced. After pressing,it was sintered for two hours at 1300°C in an argon atmosphere gas environment. Production process,microstructure analyzes were done.
