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

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.

Microstructures and Mechanical Properties of Hot-Pressed -Matrix Composites Reinforced with SiC and Particles

“…Therefore, Si 3 N 4 and SiC may be the most promising additives for use as reinforcing material for metal silicide-based composites. However, there are few papers [19] reporting the addition of SiC and Si 3 N 4 particles to improve the strength, toughness, and decrease the possibility of pest disintegration of MoSi 2 .…”
