Abstract Scope |
Highly penetrating X-ray and neutron beams available at user facilities provide means to evaluate changes in materials in-situ during thermomechanical testing and processing. The non-destructive techniques provides detailed material information at length scales ranging from atomic sizes (a few angstroms, e.g. diffraction) to the mesoscopic regime (about a micrometer, e.g. small angle scattering), as well as the bulk (e.g. texture, phase fractions and porosity). From an experimental point of view challenges in successfully applying these techniques lies in matching the probe characteristics with the material characteristics, as well as matching the time scales of the data collection and the process to be followed. For the modeling, it becomes important to get information that is relevant to parameters and physics that are included in the models, both for required inputs and for the predicted behavior during the loading/processing. The talk will present examples of successful applications, and discuss challenges faced. |
