Abstract

Precipitates observed in Ni4Mo after nickel ion irradiation between 773 and 948 K were examined by analytical electron microscopy and found to be hexagonal Mo2C. The precipitate particle size increases with irradiation time; diffraction effects from the precipitate are complex when the particles are small, but distinctly different from those due to either short- or long-range order known to occur in Ni4Mo. Formation of the precipitates in the pure binary alloy is attributed to carbon contamination during the irradiation experiment. The degree of carbon contamination was dose dependent.
