Summary

The aim of this work is to determine the thermal conductivity of QE 22 alloy and QE22 alloy reinforced by 10, 15, and 25 vol.% SiC particles in the temperature range of 20–300 °C. The interface thermal conductance of these composites is estimated by comparison of Kc/Km ratio (K is the thermal conductivity and the subscripts c and m refer to composite and matrix, respectively) obtained experimentally to that calculated according to the relation of Hasselman and Johnson. The temperature dependencies of the thermal conductivity and the thermal conductance of the interface for these three composites are compared.
