Abstract The kinetic process of precipitation in matrix of cast SiCp / Al composite was studied by differential scanning calorimetry and transmission electron microanalysis techniques. In comparison with the matrix free from SiC, an additive of SiC in composite may accelerate the precipitation of GP zone and intermediate phase S'(Al_2CuMg) and decrease the peak temperature. The enthalpy of precipitation of both GP zone and S'-phase reduces substantially. TEM analysis showed that the alloying element Mg segregates at the SiC-Al interface. Thus, the Mg nearby the interfaces in matrix depleted, and the precipitate-free zone and precipitate-sparse zone formed near the interface, the amount of precipitate decreased.

Key words: SiCp/2024 differential scanning calorimetry precipitation in matrix
