Structure images of the Cu-28 at. %Pd, Au-l7 at. %Zn and Au-16. 1at. %Mg alloys having the 2d-Cu_3Pd type structure were studied by 1 MV electron microscope. It was shown that deviation of alloy composition from stoichiometric A_3B is accommodated at the second kind boundaries; a strong tendency of avoiding the formation of nearest neighbour pairs of Zn(or Mg) atom across the boundaries is observed in the AU-Zn and Au -Mg alloys, whereas an opposite tendency is seen in the Cu-Pd alloy. Part of the deficiency of Zn (or Mg) atoms is accommodated also at the first kind boundaries.
