Abstract

The rolling texture of Cu3Au has been investigated by X-ray diffraction. At room temperature, independently of the degree of long-range order, Cu3Au developed a mixed or “hybrid” texture; it consisted of elements of each of the prototype face-centered cubic textures characterized by pure copper and 70/30 brass. However, on rolling at 77 K the alloy in the disordered state was significantly more “brass-like” than when it was fully ordered. This result may be explained by a stacking fault energy texture reversal analogous to that observed in wire drawing at low SFE. The lack of twinning (or other deformation mechanism such as slip by partial dislocations) in the ordered alloy could be responsible for this reversal.
