Originální abstrakt

The processes during which interstitial elements diffuse often against their own gradient of concentration, are labelled as up-hill diffusion. Due to the fact that namely at low temperatures 500 – 800oC when majority of welded joints of steels in power engineering equipment works on a long-term basis, diffusion of substitutive elements in comparison with interstitial elements is practically negligible, it is appropriate to use at description of diffusion of interstitial elements is practically negligible, it is appropriate to use at description of diffusion in the given system as quasi-stationary diffusion. The paper deals with a model of quasi-stationary diffusion of carbon in welded joints of steels. The model is presented in the form of engineering interpretation, the reason for such approach is its practical application. The possibility of relatively prompt prediction of carbon concentration characteristics in the neighbourhood of the boundary of welded joints of two steels A and B. Steel A represents carbon or low-alloy steel and steel B represents medium steel alloyed with element such as chromium which significantly minimises carbon thermodynamical activity.
