TiB2/AI) composites were fabricated by reaction pressing of Ti-AI-B and TiO2-Al-B systems. It is indicated that for the Ti-Al-B system, a certain amount of Al3Ti with a size of several ten μm formed in addition to TiB2, most of the in situ formed TiB2 are block-like particulates with a size of 0.1─5.0 μm, and few TiB2 are rod-like and have an aspect ratio of greater than 4. For the TiO2-Al-B system, the formation of Al3Ti is basically inhibited, and the in situ formed Al2O3 and TiB2 are approximate equal-axial particulates with a size of 0.052.0 μm. The different microstructures of two composites are accounted for.
