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.
