In order to clarify local structural characteristic of Fe-B based metallic glasses, HREM and electron diffraction studies were performed for binary Fe-B and ternary Fe-Nb-B glasses. From HREM and nano-diffraction studies, structures with "nanoscale phase separation" were observed in these metallic glasses. The bcc-type and compound-type clusters were actually found in both the glasses by nanobeam diffraction. HREM results showed, however, that the extension of the structure of nanoscale phase separation was smaller in the ternary glass, reflecting its high glass forming ability.
