Abstract

The microstructure and creep properties of coarse- and fine-grained aluminum dispersion-strengthened with 25 vol.% of 0.3 μm alumina particles are presented. Creep testing indicates that both the apparent stress exponent and the activation energy are significantly higher than those for pure aluminum. These results are compared to published data on related materials, and discussed in light of dislocation models for the threshold stress in dispersion-strengthened materials.
