The phonon scattering by vibrating dislocation dipoles and the scattering by twinboundaries are discussed to explain the thermal conductivity of deformed crystals ofbusmuth and its dilute alloys. The scattering of phonons by vibrating dislocation dipoleswas calculated by employing Ninomiya's formulae of eigenvibrations of an edgedislocation dipole, and the results were successful to explain the thermal conductivity ofbismuth crystals deformed by slip. The thermal conductivity of twinned bismuthcrystals was calculated by assuming that the scattering of phonons obeys the scatteringlaw of a long wavelength acoustic wave scattered by a plane interface between twin-related media. The results are in reasonably good agreement with the experiments.
