Abstract

Interdiffusion and structural relaxation in amorphous compositionally modulated films of Fe-Ti have been measured simultaneously. Interdiffusivity is determined by the change in X-ray modulation peak intensity upon annealing and structural relaxation is determined by the shift in X-ray peak position corresponding to the densification. The relaxation kinetics of the densification are explained by the free volume model of structural relaxation. The relaxation kinetics of the inverse diffusivity are shown to be the same as for viscosity relaxation.
