The FeCrAI-type alloys containing 15-20 wt.% Cr, 4.5-5.5 wt.% Al and small amounts of reactive elements, most frequently yttrium or zirconium, are the best oxidation resistant metallic materials at high temperatures. Into this group are classified together alloys which differ considerably taking int

Different modes of introduction of yttrium have been tested with regard to the influence on the high temperature oxidation behavior of a FeCral alloy. Y 2 O 3 sol-gel coatings, Y 2 O 3 metal-organic chemical vapor deposition (MOCVD) coatings, implanted yttrium ions and yttrium as alloying element (0
## Abstract Several routes of yttrium introduction were applied to test the high temperature oxidation performance of a FeCrAl alloy. Isothermal oxidation tests were described in a previous paper (Part I of this paper in this journal, 2004, 55, 352). Cyclic oxidation tests were performed in air und
