All of the enhanced and sometimes astonishing mechanical and radiation immune properties that have been reported and attributed to nanocrystalline and ultrafine-grained structures in metals are all highly dependent on the long term stability of the initial internal structure. This presentation will use the most advanced techniques in in-situ transmission electron microscopy and analytical modeling to elucidate the grain boundary mobility in nanocrystalline FCC metals and metal alloys bombarded with ion irradiation, mechanical loading, traditional conductive heating, as well as laser heating. The character and extent of grain growth in these four different driving conditions were observed to result in very different grain size distribution and grain boundary types. This work will be compared to classical models and the known literature.
