The antiphase domain boundary is a region in materials where ordering of atoms changes from one structural variant to another. The infuence of the internal energy excess on the dynamics of such a boundary is considered in the framework of the Onsager theory of linear response. The internal energy transport entails a temperature hump in the transition region and causes a drag effect. An evolution equation that takes into account the finite thermal conductivity is derived. An experimental setup to reveal the thermal drag is suggested. # 1998 Acta Metallurgica Inc. Published by Elsevier Science Ltd. All rights reserved.
