This thesis contributes to the fundamental process understanding in the production of perferritic and austempered ductile iron. The in-situ characterization of the phase transformation kinetics by neutron diffraction establishes a link between microstructure and mechanical properties. In addition to the influence of the alloying element Mo, the applicability of different kinetic models is investigated. Finally, the findings obtained are used to design a fatigue-resistant ADI alloy with focus on achieving the most energy-efficient manufacturing process possible.
