%X <span>The effect of addition of metallic carbides Cr<sub>3</sub>C<sub>2</sub> and Cr<sub>3</sub>C<sub>2</sub> + VC on structure and mechanical properties of WC-10</span><span> </span><span>wt%</span><span> </span><span>Co nanocomposites have been studied. After preparing and compacting of the powders under pressure of 200 MPa, the samples were sintered at temperatures of 1370ˇăC, 1410ˇăC and 1450ˇăC for 1 hour. Microstructural examinations by SEM show that the average grain size obtained for Cr<sub>3</sub>C<sub>2</sub><b> +</b> VC added alloys reduced 50 percent and also grain size dis</span><span>tribution was narrower compared to those samples without grain growth inhibitors. Furthermore, co-addition of Cr<sub>3</sub>C<sub>2</sub> and VC rise to a higher Vickers hardness and fracture toughness of the sintered alloys at 1410ˇăC.</span><span></span>
