This memorandum deals with the metallurgy and properties of thoria-strengthened nickel, a material which shows promise as a structural metal for use in the temperature range of 1900 to 2400 F where the present nickel- and cobalt-base superalloys lose most of their useful strength. Discussed in the memorandum are methods of producing dispersions in metals, and the processing variables involved in making dispersion-strengthened nickel. An entire section on the mechanical properties of thoria-strengthened nickel is included. Given in this section are tensile, creep-rupture, shear, and fatigue properties, as well as the effect of various thermal and mechanical treatments on the material. Physical-property data comprise one section of the memorandum, and oxidation resistance another. In a section on joining the following joining processes are discussed: resistance welding, flash welding, brazing, diffusion bonding by hot pressing, electron-beam welding, fusion welding, and others. In the last section of the memorandum the author presents an outlook for future developments of dispersion-strengthened nickel. (Author).
