【 摘 要 】
The composition of topmost atomic layers of single crystal solid solution (100)Cu-4 at. % Mn was studied in the range of T = 300...875 K by AES. Data on the surface composition are compared with the results for polycrystal Cu-22,5 at. % Mn, obtained in previous work. It is shown that in the nonequilibrium region segregation is determined by the diffusion length of Mn in Cu . For equilibrium state are defined the segregation energy and other thermodynamic parameters of the surface.
