The present work reports the effect of high-energy ball milling on B-Ti-C mixtures. The milling process was carried out for up to 70 h and then the milled powders were heat treated between 800 ο and 1200 οC for 1 h. The milled and heat treated powders were characterized by means of X-ray diffraction (XRD) and a scanning electron microscope (SEM). TiB2 was characterized as the only crystalline phase after milling for 6 h. B4C was formed after heat treatment of the milled powders above 1000 οC. The crystallite sizes of TiB2 varied from 57.2 nm up to 7.5 nm after milling of powders from 6 to 70 h, respectively.
