Crystallization behavior and Mossbauer studies of the R(6)-(Fe,Nb)(88)-B(6) alloys with R=Nd, Pr, Dy
We have prepared a new series of R-Fe-B alloys with R=Nd, Pr, and Dy having the Y(3)Fe(62)B(14) structure using the melt-spinning technique. This metastable phase when annealed at higher temperatures transforms to the R(2)Fe(14)B(1) alpha-Fe phase. We have studied the crystallization behavior of the...

| Zusammenfassung: | We have prepared a new series of R-Fe-B alloys with R=Nd, Pr, and Dy having the Y(3)Fe(62)B(14) structure using the melt-spinning technique. This metastable phase when annealed at higher temperatures transforms to the R(2)Fe(14)B(1) alpha-Fe phase. We have studied the crystallization behavior of these alloys. (57)Fe Mossbauer studies have shown that the as-spun samples were amorphous and the ribbons annealed at 600-620 deg C contain the metastable Y(3 )Fe(62)B(14) type structure with alpha-Fe. The analysis of the Mossbauer spectra of the R(3)Fe(62)B (14) phases has yielded average hyperfine fields of 229 kG at 295 K and 315 kG at 17 K |
