| Abstract Scope |
In-situ electron microscopy characterization techniques of nuclear materials are vital tools assisting in the fundamental understanding of the atomistic processes which give rise to the material’s response under extreme environments. Here we present in-situ transmission electron microscopy (TEM) characterization of advanced nuclear materials and their dynamic response to extreme irradiation conditions. Several material examples will be discussed including pure materials and high entropy alloys. We demonstrate irradiation damage evolution as a function of dose in terms of grain size growth, dislocation loop formation and void and bubble formation. The advantages and some limitations of the use of in-situ TEM techniques to solve nuclear materials problems and to fundamentally understand different and complex materials response to various extreme irradiation environments (including dual beams) will be presented. |
