Nucleation of ferrite in austenite: The role of crystallography

The nucleation mechanisms during solid-state phase transformations in polycrystalline materials are still not completely understood. The nucleation stage has a strong influence on the overall evolution of phase transformations, which determines the final microstructure and thereby the properties of the material. The understanding of grain nucleation is important for controlling the production process, the design of new steel grades with optimal mechanical properties, and the production of tailor-made steel. The scope of this fundamental research is to study the influence of crystallography on nucleation of the ferrite phase in the austenite phase during the transformation of austenite to ferrite in an iron-chromium-nickel alloy and a cobalt-iron alloy.Materials Science & EngineeringMechanical, Maritime and Materials Engineerin
