Abstract:45 wt.% SiC_p/6092Al, 5 wt.% β-LiAlSiO₄/6092Al and (45 wt.% SiC_p + 5 wt.% β-LiAlSiO₄ (Euc))/6092Al matrix composites were successfully fabricated by spray-forming and die forging technology. The microstructures, interface structures, and phase composition of the composites were analyzed with optical microscope (OM), scanning electron microscope (SEM), transmission electron microscope (TEM), and X-ray diffractometer (XRD). The thermal expansion properties, bending strength, and bending modulus of the composites were tested by thermal dilatometer and electro-mechanical universal testing machines, respectively. The results show that the SiC_p and β-LiAlSiO₄ (Euc) particles are uniformly distributed in the 6092Al matrix, and a strong bonding interface is formed with the Al matrix. The SiC_p/Al, and Euc/Al interfaces of the (45 wt.% SiC_p+5 wt.% Euc)/6092Al matrix composite are straight and clear. However, the interface reaction is not found. After solution treatment and artificial aging (T6), the coefficient of thermal expansion (CTE), bending strength, and bending modulus for (45 wt.% SiC_p + 5 wt.% Euc)/6092Al matrix composites are 14.68×10^-6 K^-1 in the temperature range of 303-473 K, 589 MPa, and 165 GPa, respectively.
