摘要：

Random alloys of Nb in alpha-Fe with the Nb concentration up to about 5 at.% were investigated by means of Mossbauer spectroscopy at room temperature vs. Nb concentration. A solid solution saturates at about 2.3 at.% of Nb. Non-stoichiometric Fe2Nb phase rich in Fe precipitates at higher Nb concentrations leaving a-Fe phase with about 1.6 at.% of Nb. The spin density of the iron atom is influenced in the a phase by the Nb atoms residing as nearest neighbours or second nearest neighbours. More distant impurities have no effect on the hyperfine parameters of Fe. (c) 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
