Abstract
V originále
The ThermoCalc software is presented as a tool for phase diagram calculations of the stainless steel ČSN 17 242 and progressive steel P 91. The DICTRA software is used for simulating diffusion in multiphase diffusion couple ČSN 17 242 /P 91 at temperatures ranging 500-1100stC. Diffusion simulations, made at present study, are based on an assumption that the g-phase is continuous throughout the whole diffusion couple with carbide phases as secondary spherical particles. The simulations are carried out using critically assessed thermodynamic and kinetic data taken from literature. They respect thermodynamic stabilities of all present phases. The examples of calculated phase profiles, activity and concentration profiles of all species at selected condition are shown. The obtained activity profiles imply a possibility of up-hill carbon diffusion below 1060stC.
