Abstract
An XAFS study of metallic iron at room temperature and pressures to 21.5 GPa has been performed. The data show the transition from the α (bcc) to the ε (hcp) phase. With increasing pressure a mixed phase region is found to mainly exist between 13 and 20 GPa, and between 15 and 11 GPa with decreasing pressure. We report the XAFS derived results for the coordination numbers, the near neighbor distances and the associated Debye-Waller factors.Keywords
