Mossbauer analysis of the iron-zinc intermetallic phases

Abstract

Four iron(Fe)-zinc(Zn) intermetallic phases were investigated using Mossbauer spectroscopy and XRD, in order to characterize their Mossbauer properties. Mossbauer analysis showed that the Mossbauer spectra for them were uniquely different from each other. The gamma and gamma-1 phases were composed of four subspectra, while the delta and zeta phases were consisted of three and one subspectrum, respectively. The C site of gamma phase and the D site of gamma-1 phase were included into their Mossbauer characterization. The D site of gamma phase, which has not been previously reported, was also added for its Mossbauer characterization in this study. The Mossbauer properties can be used for the phase formation and transformation studies as a function of the synthetic conditions. (C) 2003 Elsevier Science Ltd. All rights reserved.
