Abstract: The in situ formed Al2O3 and TiB2 particulates reinforced Al-3.3 wt pct Cu alloy composite hasbeen successfully fabricated by reaction pressing of TiO2, Al, B and CuO powders. The in situformed Al2O3 and TiB2 particulates with a size from 10 nm to 2 μm are unifOrmly distributedin the matrix. The composite has a tensiIe Strength of 482 MPa and an elastic modulus of103.3 GPa.
