AlMgB14 is a novel hard and brittle material which need be improved toughness for utilizing as cutting tool materials. In present study, intermetallic compound Ni3Al were attempted to dope the synthesised AlMgB14 materials. The microstructure of the AlMgB14-Ni3Al composites was analysized by scanning electron microscope (SEM) with energy dispersive X-ray spectroscopy (EDX) and an X-ray diffractometer(XRD). The density, hardness and fracture toughness of AlMgB14-Ni3Al composites were also measured. The results showed that the major phases in AlMgB14-Ni3Al composites were AlMgB14, MgAl2O4, Ni3Al and NiAl as well as W2B5. With the increasing of the amount of Ni3Al, more transgranular fractured features can be found in the fractured surface, the density of the AlMgB14-Ni3Al composites was increased, the hardness and fracture toughness of the AlMgB14-Ni3Al composites were decreased.
