In order to obtain the information on the force-distance relation for the interaction between a dislocation and a solute atom, the amplitude-dependent internal friction was measured at 1.7–30 K on Al-100 at ppm Zn and Al-50 at ppm Zn single crystals.The temperature dependence of the applied strain under a constant decrement was exactly the same for the two crystals. The data were analized by using the thermally assisted break-away theory for pinned dislocations with assuming several forms of the interaction potential. A modified Cottrell potential was considered, in which the interaction force was cut off at a critical distance close to the center of dislocation. This model was found to be able to explain the temperature dependence of the applied strain satisfactorily, and the critical distance was estimated to be 1.4 Å.
