Profile
Dr. Techn. Grethe Winther's focuses on analysis and modelling of microstructure and properties of metals.
Main activities include:
- Dislocation structures: Systematic mapping and analysis of dislocation boundaries in deformed metals based on electron microscopy data. Established the relationship between dislocation boundaries and fundamental deformation mechanisms. Formulated a general model for dislocation structure prediction.
- Deformation textures: Evaluation and development of crystal plasticity models at the grain scale based on synchrotron data (3DXRD).
- Rekrystallisation: Introduced new analysis of the orientation relationship between nuclei and the deformation microstructure.
- Mechanical properties: Modelling of mechanical properties important for industrial forming processes. Formulated a model predicting the combined effects of texture and dislocation structures.
