Abstract
We present a study of the surface segregation at the (111) surface of a ran dom Al50Zn50 alloy and a study of an AlZn alloy at the (111) surface of Al at zero temperature by means of the linear muffin-tin orbitals Green's func tion technique. We find that zinc segregates in the surface layer and that the phase separation exists in the surface solid solution of random AlZn al loys.
