ABSTRACT
High-temperature deformation in materials is highly sensitive to microstructure.
Accordingly, seeking correlations between mechanical behaviour and microstructure
represent an effective approach that can clarify issues or settle controversies related
to high-temperature deformation. There are several microstructural techniques that
can be adopted to explore the presence of these correlations. This presentation
reviews examples of the application of some microstructural techniques, especially
transmission electron microscopy (TEM), to several areas of high-temperature
deformation.
