The NiAl-based composite strengthened by TiC and Al2O3 was synthesized by thermal explosion and hot extrusion. Its microstructure and mechanical properties were investigated by XRD, OM, TEM and HRTEM. The results reveal that the NiAl-TiC- Al2O3 composite can be densified with less porosity. The NiAl grain of the composite matrix has been well refined by the TiC and Al2O3 particles. In addition, stacking fault and microtwins formed in some TiC particles and thin amorphous layer also observed along NiAl/TiC interface. Moreover Ti2AlC particle with intergrowth TiC plate inside is formed along the NiAl grain boundary.
