摘要: Abstract A previously reported formalism for ion-beam mixing is extended to include the formation of an intermediate phase as required by binary diagram. It shown that general requirements diagram can be established simply introducing discontinuities in diffusion parameters, effectively kinetics. Specifically, a self-consistent argument was developed with system five domains corresponding two terminal solid solutions, transition regions, and phase. The are justified terms free energy ΔGm. numerical solution problem bilayer geometry reproduces experimental laws: thickness increases (dose) 1 2 , total amount also .
