Evolving microstructures in carbon steel
A neutron and synchrotron radiation study

Dr. S.E. Offerman, IRI - TU Delft

A long-standing problem in the field of materials science is the understanding of the evolution of the microstructure during the formation of polycrystalline materials like metals and ceramics. The most important reasons for this are the limitations of the experimental and modeling techniques that prevent a detailed study of the grain nucleation and growth mechanisms. In this presentation unique neutron and synchrotron measurements will be discussed, which have hitherto not been realized with other techniques, on the evolution of the microstructure in the bulk of carbon steel, even down to the level of individual grains. These measurements are of vital importance for technological applications, because a better understanding of the evolution of the microstructure opens the opportunity for the industrial development of materials with superior strength and formability.
