With the findings of the preceding part II a model is established which considers dislocation and diffusion creep and which is used to simulate the creep behaviour of alloys with grain and particle coarsening during creep. It is found that the structure changes during creep give rise to a complex stress – strain rate dependence and to additional transition fields in the corresponding deformation maps which is of importance for the interpretation of practical long‐term creep results.
