Titanium matrix composites (TMC) exhibit excellent specific strength and corrosion resistance. TiB whiskers can be formed in titanium by solid-state reaction between titanium and TiB2 powders. The formation of TiB whiskers results in the improvement of tensile strength, Young's modulus and Vickers hardness. In this study, TiB reinforced pulverized or gas atomized pure titaniums were fabricated by spark plasma sintering. We focus on the effects of the powder morphology and size on the tensile properties of TiB/Ti composites. We will investigate the sintering performance and microstructures of TiB/Ti composites.

The aim of this study is to evaluated the possibility of the in-situ synthesized (TiC+TiB) reinforced titanium matrix composites (TMCs) for the application of structural materials. In-situ synthesis and casting of TMCs were carried out in a vacuum induction melting furnace with Ti and B4C. The synthesized TMCs were characterized using scanning electron microscopy, an electron probe micro-analyzer and transmission electron microscopy, and evaluated through thermodynamic calculations. The spherical TiC plus needle-like and large, many-angled facet TiB reinforced TMCs can be synthesized with Ti and B4C by a melting route.
