Abstract Amorphization was achieved by a non-equilibrium process of ion mixing of multilayered films in an immiscible Fe-Cu system with a large positive heat of formation (+19 kJ/mol). The free energy diagram of the Fe-Cu system was constructed. In calculation, the interfacial free energy, ferromagnetic effect and the structure characteristics were considered. The calculated Fe-Cu free energy diagram can explain the amorphization behavior in this immiscible system.
