Nanocompositional Electron Microscopic Analysis and Role of Grain Boundary Phase of Isotropically Oriented Nd-Fe-B Magnets
(a) TEM-BF image of the multiphase large grained nanocomposite. ((a) insert) No change in chemical composition in the EELS line scan across a GB. No separate GB-phase is detected. (b) HRTEM image of three granular phases.
