Abstract: The process of the mechanical alloying reaction between B₄C and Ti during ball milling was studied by EPMA and X-ray diffraction. It is revealed that the reaction of 3Ti+B₄C=2TiB₂+TiC can be induced by mechanical alloying within 90 min of ball milling. The XRD peaks of TiB₂+TiC are broadened with increasing ball milling time.

Key words: TiC; TiB₂; mechanical alloying
