Effects of five typical heat treatment processes on the damping properties and the damping peak of 6061Al/SiCp MMC fabricated by spray codeposition were studied. The results show that the internal friction spectra of various heat treated samples exhibit the damping peak versus temperature between 130℃ and 200℃. Furthermore, the peak temperature as well as the peak height increases with increasing frequencies. By Arrhenius equation the active energy of the damping peak can be gotten, which is above 1eV. On the other hand, different quenching treatments affect the damping peak remarkably, when the rate of cooling is above that of water quenching, the damping peak will shift to higher temperature as cooling speed is enhanced.
