Abstract

Zr-2.5Nb-xCu (x=0.2, 0.5, mass fraction, %) specimens were annealed at 580 for 50 h and 620 for 2 h after β-quenching and cold rolling, and then corroded in autoclave with 500 /10.3 MPa superheated steam. SEM and TEM equipped with EDS were employed to investigate their corrosion behaviors through analyzing the microstructures of the fracture surface of the oxide layers or of the cross-section of oxide layers. It was found that the addition of copper can improve the corrosion resistance of Zr-2.5Nb alloy, which is closely related to the increases in the fraction and size of columnar grains in the oxide film. KEY WORDS Zr-2.5Nb alloy, copper, corrosion, oxide film, microstructure
