Witrynaand is different for FCC, BCC, and HCP structures. FCC The atom in the center of a close packed plane, such as fig.3a, has six nearest neighbors in the octahedral plane above (ie B positions), and 3 below, (ie C positions). Therefore the coordination number of FCC structures is 6 + 3 + 3 = 12. BCC BCC structures have no close packed planes. Witryna17 sie 2016 · This gives 14 nearest neighbors for bcc in the big minimum vs only 12 for fcc, yielding the possibility (and reality) that the bcc phase can be slightly more stable …

WitrynaThe lower swelling observed in bcc steels relative to fcc steels is shown in this paper to be primarily a consequence of much longer transient regimes prior to the onset of steady-state swelling. Several other commonly held perceptions concerning the swelling of both bcc and fcc steels are examined in this paper and also shown to require revision.
