“…The formation of such second phases rich in alloying elements will affect their mechanical properties, corrosion resistance and as well as possible hydrogen pickup process in service. It is therefore important to understand the precipitation process and associated crystallographic phenomena and compositional redistribution [13][14][15][16] . In spite of years of investigation, such data, particularly defect evolution and crystallographic details, are yet lacking for Zr alloys containing Nb and Fe as the main alloying element.…”

Transmission electron microscopy and energy dispersive X-ray spectroscopy have been used for crystallographic and compositional characterization of nano-precipitates distributed within the α-Zr matrix of the ZIRLO alloy. Intermetallic nano-particles with the C14 Laves-phase structure were found to be the dominant precipitate phase typically larger than 60 nm in sizes, which is assigned to the Zr(Fe,Nb)2 formula with Fe and Nb being mixed on the second sublattice sites in the bracket. Stacking faults were also observed in the ternary Laves phase, together with dislocations presenting on prism planes of the matrix solid solution. Besides, some fine spherical β-Nb particles about 30 nm in size were also found to precipitate within the α-Zr grains, with the α/β interface being crystallographically coherent.

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