The fundamental momentum conservation requirement q - 0 for the Raman process is relaxed in the nanocrystal- lites (NCs), and phonons away from the Brillouin-zone center will be involved in the Raman scattering, whi...
In this paper,we report the variation of defective structure of nanocrystalline Fe-Mo-Si-B alloys with the increase of grain size.Results suggest that for the average grain size D=55 nm,microvoid-sized defects exhibit...
