Using experimental data for Harper-Dorn creep in different materials, it is demonstrated that the flow process in this creep may be dislocation glide plus climb with the climb being rate-controlling under a constant dislocation density determined by the magnitude of the Peierls stress. A rate equation is presented which may be used to predict the occurrence of Harper-Dorn creep in any crystalline material.
