The techniques of pressure hydrometallurgy have been utilized to prepare a nickel-thoria powder which can be compacted and then fabricated by rolling to yield strip with high-temperature properties superior to those of conventional nickel-base alloys.

The effects of variables in powder preparation and fabrication procedures are discussed. Tensile and stress-to-rupture properties in the 1200–2300°F range are given and examined. Both optical and electron microscopy have been employed to determine the microstructure of this material. The properties of this dispersion-strengthened nickel are interpreted in terms of the fundamental microstructure of the material as revealed by thin foil transmission electron microscopy.
