Summary:Title screen
The study demonstrates that using pre-synthesized Ti3SiC2 as a precursor is an effective strategy for fabricating high-performance MAX-phase composites. Initial porous Ti3SiC2-TiC composites were obtained by vacuum sintering of 3Ti/1.2Si/2C, Ti/1.2Si/2TiC, 2Ti/1.2SiC/1.8TiC, and 3Ti/1.2SiC/0.8C powder mixtures, and then consolidated by spark plasma sintering (SPS) with reactive Si additions. This two-step approach promoted in-situ Ti3SiC2 formation during SPS, resulting in dense Ti3SiC2-TiSi2-TiC composites with a high MAX-phase content (up to 87 vol%) and a flexural strength of 573–719 MPa – approximately 1.5 times higher than that of composites produced by direct one-step SPS. In contrast, the one-step SPS approach, while effective for producing hard Ti3SiC2-TiC-SiC composite (16.6 GPa), could not achieve comparable strength due to inherent porosity and limited MAX-phase content
