The crystallization process in an Fe48Cr15 Mo 14 C15 B6 Tm2 metallic glass has been investigated by means of nanobeam and selected area electron-diffraction techniques. We found that the first crystallization reaction proceeds through a complicated nanoscale process, that is, amorphous→χ-FeCrMo -like long-period structures→χ-FeCrMo→ M23 C6. A long-period structure began forming as an extended structure of medium range order; its periodicity gradually changed with the growing stage on annealing, and the structure finally changed into χ-FeCrMo. The common structural unit among these structures was found to be an atomic coordination polyhedron with a coordination number of 16. On the basis of the results, we discuss the phase stability of the Fe48Cr15Mo14C 15B6Tm2 metallic glass as well as its local atomic arrangements.
