Alumina-NbC composites fabricated by spark plasma sintering

The incorporation of niobium carbide in alumina-based composites has been shown to improve the properties of composite material. The main disadvantage to get a dense composite material is the necessary high sintering temperature. The spark plasma sintering (SPS) process uses a high heating and cooli...
