On the oxidation behavior of (Zr,Nb)2Fe under simulated nuclear reactor conditions
چکیده انگلیسی
The corrosion behavior of Zr alloys was affected by second phases, especially by those containing Fe and Nb. Ti2Ni-type (Zr,Nb)2Fe compound was melted and exposed to H2O2 water solution at 320 °C and 16.4 MPa for 60 h. The oxide layer was analyzed by X-ray diffraction and high-resolution transmission electron microscope (HRTEM). The formation of nano-crystalline tetragonal ZrO2 (Fe-rich area) and amorphous ZrO2 (Fe-deficient area) was observed. HRTEM analysis identified α-Fe could stabilize tetragonal ZrO2 due to the epitaxial growth. ZrxFeyNb alloys with different iron were melted and corroded similarly. The result was consistent with the proposed mechanism.
