Abstract. TiB 2 -based composites were fabricated by taking SHS with the blends of (B 4 C+Ti) and thermite in high-gravity field. XRD, FESEM and EDAX results showed that the composites mainly were consisted of fine plate-like TiB 2 , irregular TiC and (Cr,Ti) 3 B 2 solids and Al 2 O 3 inclusion particles. The introduction of high-gravity field brought about pure Ti-Cr-B-C liquid, whereas rapid solidification was a key factor for the achievement of fine-grained microstructures, which in turn was responsible for the much improved wear properties of the composites.
