Abstract
Al2O3–TiC composites were fabricated using spark plasma sintering (SPS) technology between 1300°C and 1500°C. The composite densification process starts at 950°C, with a maximum densification rate at 1170°C. After thirty minutes soaking at 1400°C, a relative density of 99.5% was achieved. Microstructure analysis reveals a submicron Al2O3 grain size and homogenous distribution of titanium carbide in the matrix. The fully dense Al2O3–20wt% TiC composite exhibits high values of fracture toughness (8.3MPam1/2), Young׳s modulus (406GPa), flexural strength (850MPa) and hardness (21GPa).
