Mössbauer spectroscopy of the Zr-rich region in Zr-Nb-Fe alloys with low Nb content
Intermetallic phases and solid solutions in the Zr-rich region of the Zr-Nb-Fe system with low Nb content are studied by Mössbauer spectroscopy complemented with X-ray diffraction, optical and scanning electron microscopy and electron microprobe analysis. The phases found in each sample were those e...
