摘要: Iron tracer diffusion was studied in soft-magnetic nanocrystalline Fe90Zr7B3 without any influence of porosity, relaxation, or grain growth. The interfacial characteristics differ substantially from boundaries metals due to the presence an intergranular amorphous phase. reduced diffusivity thin layers compared initial phase indicates effect confinement. indication a second, fast path is found and quantitatively analyzed within framework two interface-type model.
