THE FEATURES OF THE PHASE TRANSFORMATIONS IN INTERMETALLIC PHASES IN ZIRCONIUM ALLOYS

On the basis of experimental data the analysis of phase changes in intermetallic phases in alloys on the basis of zirconium (Zr – 1,03 ат.% Fe; Zr – 0,51 ат.% Fe; Zr – 0,51 ат.% Fe – М (М = Nb, Sn,Ta) is carried out. We used experimental techniques: Mössbauer spectroscopy on 57Fe nuclei in backscatt...
