Consolidation and Mechanical Properties of Nanostructured SiC from Mechanically Activated Powder by High-Frequency Induction-Heated Sintering

Article Preview

Abstract:

The rapid sintering of nanostuctured SiC hard materials was investigated with high-frequency induction heating sintering process. The advantage of this process is that it allows very quick densification to near theoretical density and prohibition of grain growth in nanostuctured materials. A dense nanostructured SiC hard material was produced with simultaneous application of 500 MPa pressure and induced current within 2 minutes. The effect of the ball milling times on the sintering behavior, grain size and mechanical properties of binderless SiC was investigated.
