Abstract
The properties of A – B binary alloys are controlled by the mixed AB interaction potentials. The interfaces between two different metals are investigated for fictive mixed potentials spreading from A-type to B-type nature. The elemental AA and BB potentials are fixed. The tendencies towards formation of ordered structures on one side, and separation of phases on the other side are discussed. A description of interatomic forces respecting metallic bonding character in many-body potentials is used. This approach can be helpful for applications of alloy potentials in models with complex structures of extended defects such as dislocations and grain boundaries and in the assessment of their behaviour.
