The control of nanocrystal formation in amorphous alloys is of particular importance for the development of advanced nanocrystalline materials. In the present study, the authors succeeded in controlling α-Fe and Nd2Fe14B nanocrystallization processes in amorphous Nd9Fe85B6 by a combination of severe plastic deformation at room temperature and subsequent thermal annealing. The α-Fe∕Nd2Fe14B nanocomposite magnets prepared by this approach possess homogeneously distributed nanocrystals with a small size, 15nm for α-Fe phase and 26nm for Nd2Fe14B, and therefore show enhanced magnetic properties as compared to those prepared by directly annealing amorphous Nd9Fe85B6.
