摘 要：The oxidation characteristics for Zircaloy-4 and Zirlo in the temperature range of 700-1200°C under steam supply condition were investigated by using a modified thermo-gravimetric analyzer.The specimens were oxidized for 3600 s at each temperature and then quenched in a furnace.The oxidation rate constants were measured from the weight gains to evaluate the oxidation behavior in Zircaloy-4 and Zirlo.The weight gain rates of Zirlo were lower than those of Zircaloy-4,leading to the low rate constants.The different oxidation behaviors between both cladding materials were considered to be due to the difference in their chemical compositions.
