Zusammenfassung:<正> Although the superlattice of Cu3Au in the Cu-Au system had been widely studied for a long time as a typical example of orderdisorder changes in alloys, yet the evidence for the existence of a similar ordered structure CuAu3 at the Au-rich side appeared only comparatively recently. Hirabayashi was the first to obtain superlattice lines in the X-ray diffraction pattern of an alloy of composition 74 at.% Au, and to confirm the extraordinary property as first pointed out by Johansson and Linde that the electric resistivity increases with the onset of order. In Hirabayashi’s work, the specimen had been annealed at 180℃ for 20
