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.
