摘要
Antiphase domain boundary is a region in materials where ordering of atoms changes from one structural variant to another. Influence of the internal energy excess on the dynamics of such 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. Experimental setup to reveal the thermal drag is suggested.
