The addition of solute to Ni has a strong influence on the dislocation-dislocation interaction processes. This effect is strongest at intermediate temperatures and is explained by a dynamic strain aging mechanism of the dislocation-arrest type. This mechanism operates in alloys which do not exhibit jerky flow and it may be possible on this basis to explain the plateau stress found in many fcc alloys.
