Representative specimens of zirconium, Zircaloy-2, vacuum-melted Zircaloy-3, and argon-melted Zircaloy-3 were corrosion tested in the as-cold- worked state and after various heat treatments; all testing was done in static autoclaves in water at 360 deg C. Weight gains were measured at regular intervals for periods as long as 364 days. Testing was discontinued in specimens when the weight gain exceeded l00 milligrams per square decimeter, or when excessive spalling occurred. No attempt was made to establish per cent of theoretical hydrogen picked up. Little or no difference in corrosion behavior was observed in the various materials when in similar conditions of cold work or heat treatment. Vacuum annealing tended to result in lower corrosion rates than air or helium. All materials had poorer corrosion resistance in the cold-worked condition than after recovery or recrystallization anneals. (auth)
