| Περίληψη: | Заглавие с экрана For the first time, laminated Nb/Ti3Al(Si)C2-TiC composites were fabricated from Nb metal foils and preceramic papers with MAX phase (Ti3Al(Si)C2) powder filler. The fabrication was performed using spark plasma sintering (SPS) at the temperature of 1250 °C, pressure of 50 MPa for 5 min. The microstructure and phase composition were analyzed by scanning electron microscopy and X-ray diffraction, respectively. The structure of composites is represented by Nb metal layers and ceramic layers separated by interdiffusion layers. It was found that the interlayers formed during SPS due to interdiffusion of Nb from metallic layer and mainly Al, Si from the MAX-phase based layer. The interdiffusion results in partial decomposition of the MAX-phase in ceramic layer. |
