| Abstract: | The microstructures and interface structures of NiAlFe TiB 2 metal matrix composite using the exothermal dispersion (XD) process have been investigated The effect and micro mechanism of iron on the compression property of the composite have also been studied The TiB 2 particles are typically single crystal, and fairly uniformly distributed The precipitation of the dendritic Fe(Ni,Al,Ti) phase in the composite significantly improves the room temperature ambient ductility The interface between the reinforcement and the matrix after compression has also been studied using high resolution transmission electron microscopy |
