Abstract
A facile self-propagating high-temperature synthesis (SHS) method for the synthesis of titanium diboride and Ti-Al-B composites are reported. In this one-step process, single-phase titanium diboride (TiB2) is formed without the presence of TiB and Ti3B4. Porous titanium diboride with particle sizes ranging between 10 and 20µm is formed. Crystallite size and lattice constants were calculated and compared with the literature. High temperatures of the exothermic reaction lead to consolidation of TiB2 particles and grain growth. TiAl-TiB2 composites were made in similar one-step synthesis procedure. Small amount of Ti3Al was observed in addition to TiAl and TiB2. The composites were heat-treated and analyzed for microstructure and hardness.
