Abstract
The diffusion of indium along [001] tin-germanium interphase twist boundaries and [001] twist grain boundaries in tin has been studied in the vicinity of the β - γ' transition in the Sn-In system. The temperature of the β - γ' transition in the interphase boundaries and in the grain boundaries is lower than that in the bulk and depends on the boundary misorientation angle. In the tin-germanium interphase boundaries, near the temperature of β - γ' boundary transition, strong violations of the arrhenius law were observed. The observed decrease of the phase transition temperature at grain boundaries and interphase boundaries is explained in terms of a prewetting transition at the boundaries.
