Abstract
A model of strain hardening is developed which shows that the large values of hardening coefficient measured during high-temperature creep are a consequence of the limited slip distances available in a well-developed 3-D dislocation network. It is predicted that the hardening coefficient should increase rapidly to a constant value during the early stages of primary creep and that this constant value should be independent of applied stress. These predictions are largely in agreement with previously published data.Keywords
