摘要：

The microstructure and mechanical properties of Ti3SiC2-SiC nanocomposite fabricated by in situ hot pressing (HP) synthesis process were studied. The results show that dense Ti3SiC2-SiC composite contained minor TiSi2 obtained by hot sintering at 1350 degrees C for 1 h. The average grain size of Ti3SiC2 was 4 mu m in length, and the size of SiC grains is about 100 nm. With its fine microstructure, the Ti3SiC2-SiC nanocomposite shows good mechanical properties.
