## Abstract An expression is obtained for the excess solute atmosphere carried by a potential well characteristic of a dislocation core and moving at constant velocity in a solid solution. The results agree with the predictions of the dissipation theorem at limiting low values of the velocity. Resu

The Gibbs adsorption isotherm and Wagner's definition of excess solute at surfaces and grain boundaries are both extended to include other crystalline defects, like dislocations and vacancies. By using a thermodynamic state function which is suitable for a partially open system, open with respect to
The extended version of the Gibbs adsorption isotherm including dislocations and vacancies is used to analyse existing experimental data. Thus phenomena and models like solid solution softening, hydrogen-enhanced local plasticity, brittleness of hydrides and superabundant vacancies could be interpre
