TiB2/7055 composite was synthesized by a new melt direct reaction from 7055-(Al-3B)-Ti system with ultrasound. The phase composition and the microstructures of the as-prepared samples were investigated by XRD, SEM and EDS. The result shows that no Al3Ti phase is in existence. With the assistance of ultrasound, grains are significant refined. Moreover, the wettability between matrix and particles is improved. The shapes of TiB2 particles are mainly hexagonal or near-spherical, and the size is about 500nm. TiB2 particles are with uniform distribution. Compared with 7055Al matrix alloy, the tensile strength of the composite reaches 303MPa, increased by 10.2%. However, the elongation is 7.3%, decreased by 4.8%.

Al-4.5 wt. % Cu matrix composites reinforced with in situ SiC particles were synthesized using direct reaction synthesis (DRS). The microstructure and tensile properties of the in situ composites were examined by optical microscopy (OM) and transmission electron microscopy (TEM). The results showed that the in situ SiC particles could be obtained through the appropriate control of the fabrication parameters. The heat released by the formation of TiC effectively promoted the formation of SiC. The size of the in situ SiC particles in the matrix was about 0.2 μm.
