Ab initio thermodynamics und kinetics in the Fe-Mn-Al-C system (A02)

点击翻译按钮获取中文摘要

Using ab initio concepts, project A2 is identifying and analyzing the mechanisms that are relevant for temperature dependencies in Mn-rich steels. The required methods for an accurate determination of thermodynamic key parameters such as free energies and stacking fault energies have been developed. They will be used within the third phase to obtain an ab initio understanding of the thermodynamics and kinetics of interface-dominated processes. Furthermore, the impact of the chemical composition on the structure and energetics of dislocations will be investigated.
