| Summary: | Title screen This work presents novel approach for fabricating composite materials based on the Ti₃AlC2 MAX-phase, TiC and Al₂O₃, using preceramic papers as a starting material. Preceramic papers with different contents of Ti₃AlC2 and Al₂O₃ were produced. The composites were consolidated by spark plasma sintering at 1150 °C under a pressure of 50 MPa. The microstructure, phase composition and mechanical properties of the composites were studied. The dense composites (2% porosity) obtained at 30 wt% Al₂O₃ exhibit bending strength of 360 ± 30 MPa and hardness of 13.5 GPa. Increasing the Al₂O₃ content to 50 and 70 wt% results in higher porosity (12% and 25%), with bending strengths of 240 ± 20 MPa and 50 ± 5 MPa, and hardness values of 6.2 GPa and 5.3 GPa, respectively Текстовый файл AM_Agreement |
