Abstract
This work describes novel Nb/Ti3Al(Si)C2-TiC laminated composites fabricated by spark plasma sintering (SPS) at 1250 °C, 50 MPa for 5 min. Preceramic papers filled with Ti3Al(Si)C2 MAX-phase and Nb foils were used as feedstock. Microstructure, phase composition and mechanical properties were evaluated by scanning electron microscopy, X-ray diffraction and three-point bending test, respectively. It was found that the reaction of preceramic paper-derived layers with Nb layers results in the formation of 16.5 µm-thick interlayers mainly composed of columnar Nb-Al intermetallic, Ti-Nb-Si and Nb-Si based phases. The laminated composites showed a brittle-ductile fracture behavior characterized by multiple deflection and branching of cracks at interfaces and plastic deformation of Nb layers. Crack deflection and delamination occur mainly near the interface between the reaction layer and ceramic layer due to the presence of more brittle silicide and carbide phases. The flexural strength of the fabricated composites was ∼350 MPa at 1.5% strain.
