Original abstract
For the group of low- to high-alloy 9-12% Cr heat-resistant steels it has been shown that there is a correlation between the carbon activity and the total chromium content, which can be used as a rough and ready criterion in the choice of filling materials in heterogeneous weld joints. To make the choice of materials still more specific the above calculation of the temperature dependence of carbon activity in individual materials of the weld joint could be resorted to, e.g. using the commercially available ThermoCalc software (the CALPHAD method) and the Steel database. More sophisticated approaches require modelling the potential diffusion processes and subsequent structure changes in a particular weld joint, which can be done using the set of DICTRA programs
