Description

To study the influence of alloying elements on the process of ageing with intermetallic phase formation in BCC-Fe base alloys of Fe-Cr-Ni-Co-Mo-W-V-Nb and Fe-Cr-Ni-Co-Mo systems a combined experimental-calculation technique is used. The study showed that Ti, Nb, W and Cr promote an increase in the amount of Laves phase, σ- and R-phases under aging. The explanation is given for the mechanism of alloying element influence on a Gibbs energy decrease. The hypothesis for higher thermodynamic stability of intermetallic phases in multicomponent alloys compared to binary ones is proposed. 4 refs., 2 figs., 3 tabs
