ELECTRONIC-STRUCTURE OF AG-CU ALLOYS

According to the correlativity between energy, volume and electronic s tructure of characteristic crystals and bound conditions of OA theory, the Gibbs energy function, atomic volume function and electronic stru cture of Ag-Cu alloys have been determined. Then the electronic struct ure and properties of disordered alloys with any composition and order ed alloys with any ordering degree can be calculated. The number of d( c), covalent electrons in the states of Ag characteristic atoms decrea ses with the increase of Cu atoms in the nearest neighbouring shell. T he number of d(c), covalent electrons in the states of Cu characterist ic atoms decreases with the increase of Ag atoms in the nearest neighb ouring shell. Such changes lead to the tendencies of atomic segregatio n and partition into two phases in the Ag-Cu system.
