The influence of sintering conditions (pressure and holding time) on the structure and mechanical properties of Ti–Si–C-system composites is investigated. A formation of the Ti3SiC2, TiC, and TiSi2 phases in the composite is confirmed by XRD analysis. Structural parameters of individual phases and mechanical characteristics of the obtained composites are determined. As found, samples S2 and S3 have superior compressive strength (σu) of 1445 MPa and 1460 MPa, respectively. At the same time, sample S3 demonstrates the highest hardness of ≅10.5 GPa (1072 HV), significantly outperforming the values obtained for S1 (≅6.7 GPa, 689 HV) and S2 (≅6.5 GPa, 677 HV).

Key words: Ti3SiC2, MAX phase, composite, XRD.
