Název v původním jazyce

On determination of the diffusion layer and penetration of substitutive element in welded joint of two different steels

Popis výsledku v původním jazyce

The article presents the calculation of diffusion layer and penetration of substitutive elements in welded joint of two different steels, based on results of measurement of concentration profile. Steels have identical structure of ferritic type; from theviewpoint of chemical composition they represent a polycomponent system. Fundamental calculation method is developed on the solution of unsteady diffusion along the straight line, both in positive and negative direction. The starting point is the secondFick's law. The input data have been obtained by experimental measurements using the method of energy dispersive (ED) X-ray microanalysis. The evaluation of concentration profiles on both sides of welded joint has been performed by means of numerical method. Non-linear regression algorithm optimising model parameters had to be used. The Levenberg - Marquardt's method has been adapted and developed for this purpose. The parameters of the model, i.e. coefficient of diffusion, the effectiv
