The lattice thermal conductivity of dilute alloys of silver and gold

The thermal conductivity of certain alloys was measured on samples which had been carefully annealed to reduce the concentration of dislocations. After subtraction of an electronic component estimated from the residual electrical resistivity, the remainder was proportional to T2 below 10°k, and agreed with Makinson'a calculation of the lattice conductivity, assuming that lattice waves of all three polarizations interact equally with conduction electrons.
