In the paper, the phase composition changes for the series of Nd10+xFe90-x
(x = 0; 0.5; 1; 1.5; 2; 2.5; 3; 3.5; 4) binary alloys, produced by long time annealing and rapid
solidification methods were investigated. X-ray diffractometry and Mössbauer spectroscopy were used to
determine the phase composition of the alloys. These structural investigations revealed the existence
of two crystalline phases in the long time annealed samples: bcc a-Fe
and rhombohedral Nd2Fe17 of the Th2Zn17-type structure.
Furthermore, the single phase region was observed for the Nd concentration above 12 at.%.
For the rapidly solidified ribbon samples, a low volume fraction of the a-Fe
and the crystalline phase of hexagonal symmetry were detected.
