During the course of this master's thesis, the interdiffusion coefficient between tungsten and iron was determined. From data obtained by means of Rutherford backscattering spectrometry, an effective diffusion coefficient was determined via finite element simulations and the Boltzman-Matano method. SEM images on FIB-cuts into a layered tungsten-iron systems reveal the formation of an intermediate phase. From its growth with respect to time, a diffusion coefficient could be determined. A simulation code, describing the formation and growth of such intermediate phases, was developed.
