Metallic random alloys can display Electronic Topological Transitions, i.e. changes of the Fermi Surface connectivity, on varying the atomic concentrations. We present a study of Ag-Pd and Cu-Pt Fermi Surfaces, based on the LDA-KKR-CPA theory, and argue that the different phase equilibria of such isoelectronic systems are related to the spectacular differences in their Fermi Surfaces.
