Abstract
The free energy of a semi-infinite model binary alloy is set up. It is described essentially by two physically identifiable parameters. On minimizing this free energy under suitable constraints in a Bragg-Williams type approximation, it is shown that the composition varies as one moves in from the surface into the bulk. This 'surface segregation' of a constituent is studied under different conditions. Agreement has been obtained with the experimental results on Ni-Au alloy.
