The effects of β and TRIPLEX heat treatment on the microstructure and on the tensile properties of in situ synthesized (TiB + La2O3)/Ti composite were studied. The phases were identified by X-ray diffraction. The microstructures of titanium matrix composite before and after heat treatment were characterized by optical microscopy. The reinforcements (TiB whiskers and La2O3) after heat treatment were observed by transmission electron microscopy (TEM). Both room temperature and high temperature (600 °C, 650 °C and 700 °C) tensile properties of the specimens were tested. The results showed that the microstructures of specimens after both β and TRIPLEX heat treatment were laminar α. The room temperature and high temperature ductility of TRIPLEX heat treatment was better than that of β heat treatment. Both TiB whiskers and La2O3 particles were stable after heat treatment.
