The study was carried out in the temperature interval 548 – 648 K. It was found that diffusion is controlled by two diffusion mechanisms and that the faster one is sensitive to thermal pre-treatment of the alloy. It was concluded that the slower diffusion mechanism is due to volume diffusion in rest amorphous phase, the faster one can be ascribed to diffusion in interface between the crystallites and rest amorphous phase.
