Lattice Thermal Conductivity of a Deformed Copper-Germanium Alloy,
Abstract
Results are presented on the isochronal annealing recovery of the 1-4K lattice thermal conductivity of a deformed Cu + 7 atomic % Ge polycrystal. The theory of the modification of dislocation thermal resistivity by solute atmospheres, due to Klemens and Ackerman, predicts a gradual recovery of the lattice conductivity with annealing temperature, up to the recrystallization temperature (700K), due to thermal dispersing of the atmospheres. No effect is observed in this alloy, suggesting that the solute atmospheres did not form upon deformation, or that there was no significant dispersal of the atmospheres by diffusion of the solute atoms away from the dislocations below the recrystallization temperature.
