Volume interdiffusion coefficient and uncertainty assessment for polycrystalline materials
Abstract : A method has been developed in order to assess small volume interdi ffusion coeffi cients from experimental Electron Probe MicroAnalysis concentration profi les of polycrystalline materials by means of Boltzmann-Matano or den Broeder methods and their complementary Hall method. These methods have been used as tools for the investigation of the quasi-binary UO2/U(1-y)PuyO(2-z) interdi ffusion, for which obtaining a solid solution in the bulk of grains is of major interest. In this paper uncertainties on the interdiff usion coefficient as a function of concentration have been computed for each method. Small volume coeffi cient measurements were enhanced by means of a small angle acquisition pro le line with respect to the interdiff usion interface.
