Abstract
The influence of Gd addition on the structural properties of Fe-Cu-Nb- Si-B nanocrystallized and amorphous alloys is studied. The crystalliza tion temperature increases and the microstructure of the annealed samp les changes. Gd addition induces the formation of Gd-Fe-B phases. In f ully crystallized Fe-Gd-Cu-Nb-Si-B alloys the alpha-Fe(Si), Fe-Nb-B, G d3Fe62B14 and Gd1.1Fe4B4 phases are observed. The evolution of the mic rostructure is followed as a function of the cumulative effects of ann ealing time and temperature. The results suggest the transformation of the metastable Gd3Fe62B14 phase into Gd1.1Fe4B4 and alpha-Fe. The hyp erfine parameters of the Gd3Fe62B14 Mossbauer contribution are reporte d.
