Abstract

In the present work, Al2O3/Ti3AlC2 composites with different composition ratios was fabricated. The composites were sintered at 1550°C from blanks produced by slip casting. The microstructure and phase composition of the samples were analysed by scanning electron microscopy and X-ray diffraction, respectively. Gas permeability tests were investigated using a gas reaction automated machine. It is shown that the porosity of composites increases with increasing Ti3AlC2 content in the raw material. The composite Ti3AlC2/Al2O3 (1/2) with the highest porosity (40 %) had a maximum hydrogen flow of 200 mol/(m2s). [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
