Two research areas are being explored in this grant, surface                    segregation in ternary alloys and phase transitions in segregated               surface layers in binary alloys.  Ternary alloy systems included                in the program are nickel-silver-palladium, nickel-silver-gold,                 and nickel-gold-palladium.  These alloy systems are specially                   selected for their simplicity and segregation tendencies.  The                  binary systems under examination include copper-silver, nickel-                 silver, iron-copper, and iron-gold.  These latter alloy systems                 are likely to show surface phase transitions.  Polycrystalline                  and single crystal samples are required in the research.                        Modelling of the observed behavior is based on the Monte Carlo                  simulation using the Embedded Atom Method on a supercomputer.
