Evaluation of concentration dependent diffusivities of manganese in the diffusion joint Fe/FeMn-steel by means of mathematical-analytical methods

Original language description

The aim of the work was to study an interaction of the FeMn alloy with pure iron from the view of diffusion processes. For that purpose diffusion joints Fe/FeMn-steel were created and long-term heated at the temperatures of 800, 900 and 1050°C. Dependences of diffusivities of Mn on its concentration were calculated from concentration profiles of manganese after diffusion heating applying three analytical methods. In the first method constant values of diffusivities for both Fe and steel were taken intoaccount. In the second case a modified Matano-Boltzmann method utilizing polynomials was applied, which simplifies solution in numerous cases. The third method performs the solution of non-linear equation of diffusion on the assumption of a linear dependence of diffusivity on concentration applying a procedure based on perturbation calculus.
