Abstract

TiN nanocomposite powders with various morphologies were synthesized by DC arc-plasma method from Ti-Si ingot under N2-H2-Ar atmosphere. Microstructures of powders were characterized by powder X-ray diffraction method and transmission electron microscopy with compositional analysis, then morphologies by three-dimensional electron tomography. It was found that the powders were consisted of TiN nanoparticles covered by Ti5Si3 nanoparticles, which possibly suppressed the growth of facets and controlled the final morphologies of TiN-Ti5Si3 nanocomposite.
