Abstract
The high-density Ti3SiC2-SiC composites with different SiC volume contents were fabricated by hot pressing technique under 35 MPa in a vacuum atmosphere at 1550 °C for 30 min. Microstructural observation showed that the distribution of SiC particulates in the Ti3SiC2 matrix was uniform which improved the hardness of Ti3SiC2–20 vol% SiC sample (13.9 GPa), compared to monolithic Ti3SiC2 (7.1 GPa). The sample containing 15 vol% SiC showed the highest flexural strength value, compared to the other Ti3SiC2-SiC samples and the monolithic Ti3SiC2. The fracture toughness of the Ti3SiC2-SiC samples was also lower than that of the monolithic Ti3SiC2 MAX phase.
