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.
