Abstract

This paper describes the fabrication and high-temperature mechanical properties of functionally graded materials (FGM) based on preceramic papers with Ti3Si(Al)C2 and Ti3Al(Si)C2 powder fillers. The FGMs with different architectures were fabricated by spark plasma sintering at a temperature of 1050°C and a pressure of 50 MPa. Mechanical testing of composites at 25℃ and 1050℃ demonstrated the brittle to plastic transition of fracture mechanism. At 1050 ℃ FGMs demonstrated strain for up to 1.5 % and flexural strength about 200 MPa. Due to migration of Al from A-site of MAX-phases and formation of Al2O3 a crack healing was noted after high-temperature mechanical tests.
