Modelling of the carbon diffusion coefficients temperature dependence in the welded joint of steels
Řeháčková, L. ; Dobrovská, J. ; Million, Bořivoj ; Stránský, K.
This contribution contains the results of measurement of carbon redistribution ithe welded joint of low-alloy CrNiMoV steel and low-alloy Si steel. The measurements was carried out in the range of temperatures 500-1000°C. On the basis of the measured concentration data the carbon diffusion coefficients were calculated and also their temperature dependences were determined
On modelling of the diffusion phenomena in the selected welded joints of steels
Řeháčková, L. ; Million, Bořivoj ; Dobrovská, J. ; Stránský, K.
Measurement of carbon redistribution was carried out in temperature range 500-750oC in two types of the welded joints (low-alloy Si steel/alloy CrNiMoV steel and low-alloy Si steel/ austenitic Cr18Ni9 steel). For approximation of the measured concentrations of carbon there were applied the relations representing solution of the stationary model of carbon redistribution i.e. classical method of solution of diffusion with help of the error function.
