| Outline of Final Research Achievements |
This project has the objective of determining the fundamental principles of microstructural modification during solidification and building a macro-micro-coupled model of microstructure evolution supported by time-resolved & in-situ observations and X-ray florescence analysis using synchrotron radiation X-rays. Specific outcomes include 1) selecting solidification sequences and morphologies in Sn, Al and Fe alloys through the addition of trace elements such as Sr/Eu in Al-Si 2) understanding the role of trace elements and micro-alloying in modification, 3) understanding the interactions between solid grains during deformation and the resultant characteristics of the semisolid microstructure and 4) development of computational materials science approaches describing the refinement of eutectic Si in Al-Si alloys and the morphology selection in Fe alloys. The macro-micro-coupled model for microstructure evolution, deformation and segregation was developed by using the combined results.
