  In the paper, steels are studied that are mostly used in technical practice as base materials, filler metals, and consumable electrodes in the design of dissimilar weld joints. These steels differ mainly in the content of Cr, Mo, V, W, and N. It is explained and emphasized in the paper that the effect cannot be underrated of thermodynamics, diffusion and phase transformations on the stability of dissimilar weld joints that are exposed to temperatures of over ca. 500oC during operation. For all the materials under study the carbon activity at 600oC is given as calculated by the CALPHAD method, and a correlation is shown to exist between the carbon activity and the total chromium content. This correlation can be used as a most general alternative in the selection of filler metals or consumable electrodes in the design of dissimilar weld joints. The primary goal of the paper is, however, to present a more sophisticated alternative based on a mutual comparison of the temperature dependence of the carbon activities of the base alloys, filler metals and consumable electrodes under consideration. This alternative is suitable for routine engineering purposes. Attention is also drawn to the currently most advanced alternative, which enables predicting the redistribution of elements and phases after prolonged exposure

  This paper addresses the issue of C and N redistribution in weld joints of creep-resistant chromium steels. The redistribution of C and N was measured using the wave-dispersive X-ray method. The conditions of the long-term diffusion annealing process were: temperature 575, 625 and 700 oC; time 10, 100, 1 000 and 5 000 hours. It was ascertained that C and N diffused from the low-alloy steels to the high-alloy steel P91. The carbon diffusion coefficients in the individual steels of 15128/P91 and SK3STC/P91 weld joints, the ratio between the thermodynamic activity coefficients of carbon in joints, the diffusion interaction parameters , and their temperature dependencies were estimated from carbon concentration curves. The paper also contains a microstructure analysis of decarburized and carburized zones in the weld joints studied.
