TiB2/TiC nanocomposite powder was fabricated via high-energy ball milling p
rocessing, and microstructure development of the powder mixtures was monito
red by X-ray diffraction, transmission electron microscopy. Ball milling B4
C and elemental Ti powder mixture at ambient temperature resulted in the fo
rmation of TiC prior to the formation of TiB2. The bulk of TiC and TiB2 for
mation accomplished after 5 h of milling. The final product consisted of na
nosized TiC particles and microscale TiB2 particles. (C) 2001 Elsevier Scie
