On Mathematical Modelling of the Diffusion Characteristics in the close Vicinity of Two Steels Welded Joint
This paper deals with the quantitative evaluation of temperature and time effect on the concentration distribution of the substitutive elements in the vicinity of the welded joint. The calculations were performed for the weld of two different steels. The measurement of the concentration profiles of the elements in the weld was evaluated by the numerical optimalisation methods using the 2nd Fick’s law. The output of calculations defines quantitatively two terms: diffusion and penetration layers.
