The Al-TiAl_3 compound materials were prepared by depositing molten Al droplets onto the Ti powders layer at 350℃. The results show that the stoichiometric TiAl_3 phase is the only Ti-Al intermetallic compound formed during the reaction process. The microstructure analysis shows that the TiAl_3 particles disperse in an Al matrix.The results of the compressive tests of the specimens at room temperature show that the reacted Al-TiAl_3 compound has higher compressive strength of 594.7 MPa and fracture strain of 13.5%.
