In-situ study of the influence of alloying elements on the kinetics and mechanism of the peritectic phase transition in steel

This thesis covers a wide range of phenomena that are related to the peritectic phase transition in iron alloys: the primary solidification of the pro-peritectic solid phase, the nucleation of the peritectic phase at the parent liquid/solid interface and the rate and mechanism of the peritectic reaction as well as the subsequent peritectic transformation. A holistic approach was followed in order to not only investigate and characterize these different aspects individually, but rather to better understand the interconnection between these seemingly diverse phenomena in addition to gaining a more comprehensive understanding of this industrially important phase transition
