An apparent stress exponent, <i>n</i><sub>ap</sub>, of 7.8 and an apparent activation energy, <i>Q</i><sub>ap</sub>, of 697 kJ/mole was obtained for this material. These values are approximately double than those for the non reinforced material. The dislocation-dispersoid interaction model, termed "<i>ñ</i> model", considers that this interaction merely raises the stress exponent associated to the non reinforced matrix by a value of <i>ñ</i>. Consequently, the apparent activation energy value is simultaneously raised. The ñ model predicts accurately the experimental data and presents advantages for analysing the creep behaviour of the dispersion strengthened materials.}, number={Extra}, journal={Revista de Metalurgia}, author={Carreño, F. and Ruano, O.
