Correlations between High-Temperature Deformation and Microstructure

摘要

High-temperature deformation in materials is often highly sensitive to microstructure. Accordingly, seeking correlations between mechanical behavior and microstructure represents an effective approach that can clarify issues or settle controversies related to high-temperature deformation. While there are several microstructural techniques that can be adopted to explore the presence of these correlations, transmission electron microscopy (TEM) has proven to be a powerful tool that can provide guiding information regarding the details of the microstructure that accompany deformation. This paper discusses examples of the application of TEM to several areas of high-temperature deformation.
