TiB2/TiC nanocomposite powder fabricated via high energy ball milling

TiB2/TiC nanocomposite powder was fabricated via high-energy ball milling processing, and microstructure development of the powder mixtures was monitored by X-ray diffraction, transmission electron microscopy. Ball milling B4C and elemental Ti powder mixture at ambient temperature resulted in the formation of TiC prior to the formation of TiB2. The bulk of TiC and TiB2 formation accomplished after 5 h of milling. The final product consisted of nanosized TiC particles and microscale TiB2 particles.
