Abstract
Mössbauer spectroscopy of 57 Fe was used to study the content and structure of precipitates in different thermal-treated Zircaloy-4 specimens. The spectra of Zircaloy-4 have two sets of peaks. One of them can be ascribed to precipitates of intermetallic compound Zr(Cr,Fe) 2. The structure of the specimen is changed by thermal treatment. The area of the Mössbauer peak is also changed. Content of Zr(Cr,Fe) 2 in a water quenched sample is the same as that in an as-received (50% cold worked) sample. The content of alloying element-iron in matrix between precipitates is not an important factor which has an influence on corrosion resistance of Zircaloy-4.
