The microstructure of an ordered Fe-37 at% Al intermetallic compound with Ce, La and Zr additions has been investigated after annealing in the temperature range 1023-1533 K. The order-disorder critical temperature determined by X-ray diffractometry was found to be approximate to 1540 K. Second phases containing Ce, La and Zr have been identified as Al(8)XFe(4), Al(4)X (X=Ce, La) and Al6Fe6Zr. Size, morphology and distribution of these phases after different thermal treatments have been described by means of SEM observations with EDS microanalysis.

Abstract
The microstructure of an ordered Fe-37 at% Al intermetallic compound with Ce, La and Zr additions has been investigated after annealing in the temperature range 1023-1533 K. The order-disorder critical temperature determined by X-ray diffractometry was found to be approximate to 1540 K. Second phases containing Ce, La and Zr have been identified as Al(8)XFe(4), Al(4)X (X=Ce, La) and Al6Fe6Zr. Size, morphology and distribution of these phases after different thermal treatments have been described by means of SEM observations with EDS microanalysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
