Equilibrium surface segregation in copper-aluminum alloys has been observed by use of Auger electron spectroscopy (AES) and low energy elsctron diffraction. The alloys studied were solid solutions of aluminum in copper having compositions of 1,5 and 10 at. 'A aluminum. All samples were single crysta
Equilibrtum surface segregation concentrations have been measured for tm diluted in aluminmm wrth bulk concentrattons of about 2 x 10-s atom per aluminium atom, between 623 and 893 K. MacLean's model fits the experimental results well and gives a segregatton energy q,, = -77 kJ mole-' between 293 K
