Abstract

Local atomic structures of Pd- and Fe-based metallic glasses (Pd 40Ni4OP2O and Fe84Nb 7B9)WeFe investigated by means of transmission electron microscopy (TEM). In these typical metallic glasses, local structures of nanoscale phase separation were observed using high-resolution TEM and nanobeam electron diffraction. A structural modeling of the Pd-based metallic glass with the observed local structures was also performed with the help of computer simulation which explained an energy-filtered electron diffraction data. The obtained results show that the comprehensive TEM study is useful to understand nanoscale structural organizations in metallic glasses.
