The Band Structure and the Anomalous Alloying Behavior of Noble Metal Based Systems

Alloying behavior is investigated by considering the change of the original electronic structures of the constituent metals and the interactions initiated in between. A co-resonance model is proposed to depict the physical picture of alloy phase formation. It is shown that the model can explain the intrigue alloying behaviors of noble–transition metal systems. Les comportements alliants sont examine par la consideration sur le changement des structures electroniques originals des meteaux constituants et sur les interactions entre les atoms des meteaux constituants. Un modele de la co-resonance est propose pour peindre la peindre physique de la formation des phases alliants. Il est montre que le modele sait expliquer les comportements alliants intrigants des systemes des noble–transition meteaux.
