Breakaway oxidation of zirconium alloys exposed to steam around 1000 °C
Résumé
The breakaway oxidation of Zircaloy-4 and M5Framatome alloys oxidized in flowing steam around 1000 °C was
studied. The influences of oxidation temperature between 950 and 1050 °C, one-side versus two-side oxidation
and chemical variations around the nominal composition of M5Framatome were investigated. Breakaway oxidation
is sensitive to the oxidation temperature, the material and the oxidation type. A phenomenological mechanism
for breakaway oxidation is postulated on the basis of microstructural and microchemical analyses.
