| Zusammenfassung: | Title screen In this work, laminated Nb/Ti3Al(Si)C2-TiC-Al2O3 metal-ceramic composites were fabricated for the first time using the hot-pressing (HP) method. The starting materials consisted of Nb metal foils and Ti3Al(Si)C2 highly filled preceramic papers. The composites were sintered at 1250 °C under 50 MPa for 60 min. The microstructure and phase composition were studied using scanning electron microscopy and X-ray diffraction, while the mechanical properties were evaluated through Vickers method and three-point bending tests. The obtained results were compared with those of composites fabricated by spark plasma sintering (SPS). A heterophase reaction layer with an average thickness of 22 μm was formed at the ceramic/metal interface, which was slightly thicker than that obtained by SPS. The stronger decomposition of the MAX phase during HP inhibited densification and altered interfacial reaction kinetics. The obtained quasi-ductility (deformation up to 5%) can be explained by the delocalized plastic deformation of Nb layers caused by multiple cracks in Ti3Al(Si)C2-based layers Текстовый файл AM_Agreement |
