It was noted that the few available examples of pure climb-plasticity indicated that the stress dependence of the corresponding dislocation velocity was larger than the simple proportionality predicted by classical models. A possible explanation was proposed here on the basis of a comparison with dislocation glide in semiconductors. It was shown that high-temperature creep of several materials, in particular superalloys, might be controlled by the same process. On the Stress Exponent of Dislocation Climb Velocity.
