ALUMINUM CONTAINING FECRAL ALLOY

摘要

PURPOSE: FeCrAl alloy containing aluminum is provided to enhance corrosion resistance and oxidation for a liquid Pb or Pb-Bi cooling material without serious brittleness within a temperature range of 300-600°C. CONSTITUTION: FeCrAl alloy containing aluminum consists of Cr of 9.5-12 weight% and Al of 4-5 weight%. The FeCrAl alloy forms an external protecting oxidizing layer. The oxidizing layer is an aluminum oxide layer(Al2O3). The FeCrAl alloy comprises Mo of 0.7 weight%, Zr of 0.03 weight%, B of 0.007 weight%, and C of 0.01 weight%. The FeCrAl alloy is used as the structural material and tubing material of an energy system including a nuclear reactor. The nuclear reactor is a liquid Pb and Pb-Bi cooling nuclear reactor.
