Abstract
The synthesis of high performance WC-Co cemented carbides which can be efficiently used in the cutting tool industry. WC with different particle sizes and different grain growth inhibitors were consolidated through spark plasma sintering technique and to form a cemented carbide with best combination of mechanical properties. VC and CrCare included as grain growth inhibitors in different amounts and combination to the WC-Co powder composition. Higher amount of inhibitors results in lower grain sizes and higher hardness values, however adding more than a crucial amount was observed to degrade the mechanical properties.
