摘要：

High-resolution electron microscopy has been used to investigate the structure of coherent twin boundaries in ordered Cu3Au. Apart from confirming the previously established symmetric structure S and asymmetric structure A, the composition of atomic columns in the boundary has been examined. Evidence is presented for a new asymmetric structure which differs from structure A in the arrangement of Au and Cu atoms in the atomic columns at the boundary.
