Abstract
Measurements of the surface composition of a Cu-Ni alloy using Auger electrons with different average escape depths reveal sputter-induced subsurface compositional changes at elevated temperatures which are larger than those produced directly at the surface by preferential sputtering. The compositional gradients which are produced extend to significantly greater depths than have been considered previously.Keywords
