Abstract

A Ni-Mo alloy treated in a solution was annealed at 1073K for 24 hours to obtain a two-phase nanostructure. It is composed of the nickel matrix with a face-centered cubic (fcc) structure and Ni4Mo precipitates with a D1a body-centered tetragonal superstructure. When Ni4Mo precipitates are formed in the nickel matrix, six types of orientation relationships exist between the precipitates and the matrix. Its etchant was an electrolysis polishing solution with composition CH3OH : HSO4 = 3:1 and mthe magnification of the dark-field image was 26000X.
