Abstract
Thermal properties involving thermal diffusivity and conductivity of reinforced and unreinforced QE22 alloy were investigated in the temperature range from 20 to 300 °C. The thermal diffusivity of unreinforced QE22 alloy is practically independent of temperature while that of the particle reinforced QE22 alloys decreases with increasing temperature. In the same temperature range the addition of the SiC particles in the QE22 alloy causes a reduction in the thermal conductivity. The experimental data are discussed.
