Abstract
Assisted by the interfacial free energy, metastable and fcc phases were for med by room temperature 200 keV xenon ion mixing of nano-sized multilayers in the Co-Ag system being immiscible at equilibrium and characterized by a large positive heat of formation. The formation mechanism of metastable pha ses is discussed in terms of the far-from-equilibrium process of ion mixing , the role of the interfacial free energy in enhancing alloying capability and the effect of valence electrons.
