Table 1 Test Matrix for Oxidation of Samples for Post-Quench Ductility Tests. The times and ECR values listed correspond to those calculated using the Cathcart-Pawel weight gain correlation, a nominal wall thickness of 0.57 mm, and two-sided isothermal oxidation in steam. The relationship between ECR (%) and normalized weight gain (Aw in mg/cm 2 ) is ECR = 1.538 Aw for 0.57-mm-thick cladding samples.

Table 2 Weight Gain (Aw in mg/cm2 ) and Measured ECR (%) Values for Zry-4 and MS Oxidized in Steam at 1200'C. ECR = 1.538 Aw for Zry-4 (0.57-mm wall) and ECR =

1.437 Aw for MS (0.61-mm wall). Alloys were oxidized for the same ramp rate, approximate hold time and cooldown rate for each target ECR value.
