In-situ TEM observations of the coarsening of a nanolamellar structure in a cobalt based magnetic alloy

Grain boundary migration during abnormal grain growth in nanocrystalline Ni

“…In situ TEM annealing has been used to investigate grain growth of nanocrystalline materials in a number of studies [9,[20][21][22][23][24][25][26][27][28], but most [9,[20][21][22][23][24][25][26][27] have not reported this type of migration behaviour. One possible explanation stems from differences in sampling rates.…”
