| The project deals with the influence of the atomic traps on kinetics of diffusion of interstitial components and consequences to kinetics of diffusional phase transformations. Carbon is an important interstitial component in steels and interacts with foreign atoms like chromium, to which it can be bond significantly. A number of models describing the energetics of trapping by foreign atom have been developed and the consequences of trapping on diffusion kinetics have been demonstrated. Based on the knowledge of chemical potentials of carbon obtained by CALPHAD method the models have been utilized for determination of the depth of trap for carbon due to foreign atoms of different components. A very good agreement with the open literature has been obtained. |
