Effect of Sintering Time on the Mechanical Properties of WC-8Co Cemented Carbide for Friction Stir Welding Tool

Abstract:

WC-8Co cemented carbide specimens were prepared via vacuum sintering. The influences of sintering time on phase composition, microstructure and mechanical properties of WC-8Co cemented carbide were investigated. The results show that dense specimens were obtained in the sintering time range of 15min~60min and the relative density reached over 95%. Only WC and Co₃W₃C (γ-phase) were detected by XRD without any else phases, even though Co. With the ascended sintering time, the transverse rupture strength (TRS) increased and hardness ascended to peak value and then descended. WC-Co cemented carbide with excellent mechanical properties (HRA>90, TRS~630MPa and K_IC>7MPa·m^1/2) were obtained. It would be a good candidate for applications of friction stir welding tool.
