A recent development in powder metallurgy technology, known as mechanical alloying (1), can find applications in alloys which cannot be manufactured by conventional processes, due to high melting temperatures, chemical incompatibility of constituents in the melt, or high reactivity. The process has been utilized in the production of a nickel-base superalloy and a nickel-base solid solution which contain dispersions of fine and inert oxide particles for high temperature strength. As part of a study of the creep and stress rupture behavior of these alloys, the as-received and crept microstructures have been examined using the transmission electron microscope. This note discusses the fine-scale microstructure of the mechanically alloyed oxide dispersion strengthened (ODS) nickel-base solid solution.The alloy has a nominal chemical composition in weight percent of Ni - 20Cr - 0.5Ti - 0.3A1 with O.6Y2O3 oxide particles.
