摘要：
Ductile and microcrystalline thin Fe-Cr-Al foils with an elevated aluminum content up to 12 wt.-% were produced by a rapid solidification process. Alloys with different compositions were tested in isothermal oxidation experiments (He-O2, p(O2) = 133 mbar, T = 1273 K) and in cyclic oxidation experiments (dry air). The rapidly solidified alloys show a better oxidation resistance compared to conventionally rolled material. Cerium addition to the alloy leads to an improved oxide adhesion onto the substrate. The oxidation resistance is further improved by increasing the aluminum and decreasing the chromium content of the alloy.
