Abstract : Dispersion-strengthened metals offer potential usefulness at temperatures up to ninety percent of their melting temperatures because of their outstanding mechanical stability at elevated temperatures. In addition, most physical and chemical properties are relatively unaffected by the presence of an inert dispersion. Thus, design engineers may be able to select the base metal alloy for properties other than its strength and then incorporate a dispersion in it to obtain the required strength. At present, dispersion-strengthened alloys of aluminum, copper, nickel, and tungsten are commercially available, and alloys of several other refractory, ferrous, and nonferrous metals are being developed. The metallurgical and design characteristics of these alloys are reviewed in this paper. (Author)
