ABSTRACT |
The low mechanical properties of SiC limit its wide application despite many attractive properties. To improve the mechanical properties, a second phase has been generally added to make a nanostructured composite. In this respect, graphene was evaluated as the reinforcing agent of SiC. SiC-graphene composites were sintered within 2 min by high-frequency induction heating under a pressure of 80 MPa. The rapid consolidation method allowed the retainment of the nano-scale microstructure by inhibiting the grain growth. The effect of graphene content on the microstructure and hardness of the SiC-graphene composite was investigated using FE-SEM and Vickers hardness tester. |
