TiB_2/TiC Nano-Composite Powder Fabricated via High Energy Milling

Jian Li

Abstract

The process and the mechanism of TiB2/TiC nano-composite powder fabricated via high energy milling were studied, and as-prepared powders were characterized by TIM and XRD techniques. The results show that Ti can react with B4C during milling process, and TiC is firstly produced, TiB2/TiC particles formed after 5 hours' milling. TiB2 and TiC phases co-exist in following long time milling. After 30 hours' milling, nanosized TiC particles with a diameter of 8 urn are located in TiB2 particles with a size of 100~200nm.
