ABSTRACT
In the fall of 1986 we were invited by Professor Ochiai to edit a booklength chapter discussing the current state of knowledge of dispersion-strengthened alloys. This task was gladly undertaken because of our belief that dispersion strengthening offers much potential to develop materials with unique thermophysical and mechanical properties. Although interest in dispersion-strengthened materials, oxide dispersion-strengthened alloys in particular, has waned in the last few years at the Lewis Research Center, we both felt that there will be renewed interest in dispersion-strengthened materials in light of the extreme operating conditions being envisioned for the next generation of aircraft, such as the proposed hypersonic vehicles. Therefore a careful review of the literature combined with some speculation, if possible, on future work areas seemed appropriate and could serve as a starting point for new efforts in dispersion-strengthened materials.
