TiB2/TiC Nano-Composite Powder Fabricated via High Energy Milling

Abstract

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.

Key words: high energy milling, boron carbide, titanium carbide, titanium boron
