Book excerpt: Surface segregation of aluminum has been observed in copper-aluminum alloys by use of LEED and Auger electron spectroscopy studies. The alloys were solid solutions of aluminum in copper having compositions of 1, 5, and 10 atomic percent aluminum. All samples were single crystals oriented in the (111) direction. Surface concentrations five times that in the bulk were observed. LEED and characteristic loss data gave confirming evidence of surface composition changes. Surface concentration increased with temperature on heating to 700 [degree] C.
