ABSTRACT
Dispersion-strengthened (DS) aluminum alloys are interesting to metallurgists and engineers because they exhibit excellent combinations of properties compared with conventional aluminum alloys. Foremost of these properties are elevated-temperature strength and thermal stability. In specific applications, such as in nuclear reactors, other properties including corrosion resistance, fuel compatibility, and resistance to irradiation damage are also important. Extensive investigation has been performed to develop these aluminum alloys over the past 40 years. It is the purpose of this chapter to provide a review of these developments with emphasis on commercially produced materials, both past and present. Examples of experimental alloys are cited where appropriate.
