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
