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.

在35 MPa，1550°C，真空条件下30 min，采用热压技术制备了不同SiC体积含量的高密度Ti ₃ SiC ₂ -SiC复合材料。显微组织观察表明，与整体式Ti ₃ SiC ₂（7.1 GPa）相比，Ti ₃ SiC ₂基体中SiC颗粒的分布均匀，从而提高了Ti ₃ SiC ₂ -20 vol％SiC样品（13.9 GPa）的硬度。与其他Ti ₃ SiC ₂ -SiC样品和整体式Ti ₃ SiC ₂相比，包含15 vol％SiC的样品显示出最高的弯曲强度值。Ti ₃ SiC ₂ -SiC样品的断裂韧性也低于整体式Ti ₃ SiC ₂ MAX相。
