Abstract
The reaction of zinc vapor with Zircaloy-4 and nuclear grade zirconium was investigated with various analytical techniques: optical metallography, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction. Based on the results, the Zr-rich part of the Zn-Zr phase diagram was revised. The eutectoid decomposition of (Beta Zr)occurs at a lower temperature, 718 degrees C plus or minus 6 degrees C with a composition of X (sub Zr) = 0.865. The solubility of Zn in (alpha Zr) was determined to be at x(Sub Zn) = 0.0236 a maximum at 725 degrees C. The intermetallic phase ZnZr(sub2) was observed to occur in samples heat treated at 712 degrees C and 725 degrees C, but not in those heat treated at 700 degress C and 775 degrees C.Citation
