摘要

The microstructure and isothermal oxidation kinetics of Zr-Nb-Cu alloy under water vapor environment in the temperature range from 700 to 1000℃ were studied, and the evolution laws of oxide film macro-morphologies and microstructures were also analyzed. The results show that the mass gain curves of water vapor oxidation of the alloy between 700 and 900℃ are in accordance with parabolic law, while the curve deviates from the parabolic law at 1000℃. According to the oxidation mass gain curves, the oxidation activation energy Q, and the expressions of the parabolic rate constant K_p and the mass gain W were calculated. The oxide film structure analysis indicates that the higher the oxidation temperature, the more obvious the crack and bulge of oxide film.
