• Cu-Ag alloy
• orientation relationship
• interfacial structure

A eutectic Cu-71.8%Ag (mass fraction) alloy was prepared by conventional process of fusion casting. There are approximate 50% of stepped phase interfaces with the step plane surface parallel to (111) and an orientation relationship between phases Cu and Ag symmetrized to the stepped interface in the eutectic structure. The stepped interfaces have a height equal to the average interplanar spacing of (111)(Cu) and (111)(Ag) and the widths equal to the interplanar spacing of 3-4 (11 (1) over bar)(Cu). A coincident lattice site of Cu and Ag atoms can exist at the stepped interfaces at regular intervals of 3-4 (11 (1) over bar)(Cu).
