抄録

The oxidation behavior of Zr2(Fe, Ni) precipitate in Zircaloy-2 was examined by microprobe Auger electron analysis focussing attention on the oxidation behavior of iron and nickel. In the pre-transition period, the iron oxide was formed only on the top surface of zirconium oxide layer of the precipitate and the thickness of iron oxide layer increased with the oxidation time, and nickel was oxidized via dissolution in the matrix zirconium oxide near the top surface. In the post-transition period, the oxidation of iron and nickel proceeded also inside the oxide layer. Such variety of oxidation behavior of iron and nickel between the pre- and post-transition period was attributed to the situation whether the oxygen potential gradient existed or not in the matrix zirconium oxide layer.
