    Description / Table of Contents: Vergleich der Oxydation von Fe-Cr, Ni-Cr und Co-Cr in Sauerstoff und WasserdampfDie Geschwindigkeit und der Verlauf der Oxydation zahlreicher Legierungen aus Fe-Cr, Ni-Cr und Co-Cr in Sauerstoff (1 at) und Wasserdampf (0,1 at) + Argon (0,9 at) + Spuren von Lu# als Verunreinigung bei 1000°C werden unter Verwendung von weitgehend aus einem einzigen Laboratorium stammenden Daten verglichen. Die kennzeichnenden Eigenschaften der Oxydationsmechanismen für spezifische Legierungsgruppen werden im Lichte der verfügbaren Kenntnisse über die Legierungs- und Oxid- eigenschaften betrachtet, welche die Oxydationsmechanismen bestimmen.
    Notes: The rates and modes of oxidation of a wide range of pure Fe-Cr, Ni-Cr and Co-Cr alloys in 1 atm oxygen, and in 0.1 atm water vapour/0.9 atm argon contaminated with traces of air, at 1000°C are compared, using data originating largely from a single laboratory. The main features of the mechanisms of oxidation for specific groups of alloys are considered in the light of existing knowledge on the alloy and oxide Properties determining these mechanisms.

    Description / Table of Contents: Das Oxidationsverhalten von ODS-EisenaluminidenDispersionslegierungen der Zusammensetzung Fe-28at%Al-2at%Cr wurden pulvermetallurgisch mit anschließender Heißextrusion hergestellt. Der Basislegierung wurden verschiedene stabile Oxide beigemengt, um den Effekt dieser Dotierungen auf das Oxidationsverhalten bei 1200°C in Luft und in Sauerstoff zu beurteilen. Eine Al2O3-Dispersion glättete die α-Al2O3-Schicht, aber erzeugte keinen der anderen Effekte reaktiver Elemente und hatte einen ungünstigen Einfluß auf das Langzeit-Oxidationsverhalten. Eine Y2O3-Dispersion verbesserte die Haftung der Aluminiumoxid-Schicht bei 1200°C und 1300°C im Vergleich zur Zugabe einer Zr-Legierung. Jedoch war die Wirksamkeit einer Y2O3-Dispersion in Fe3Al in Bezug auf die Haftung der Oxidschicht nicht so wirksam wie bei FeCrAl. Dieses schlechtere Verhalten hängt mit einer stärkeren Void-Bildung bei ODS-Fe3Al an der Grenzfläche zur Oxidschicht zusammen.
    Notes: Oxide-dispersed Fe-28at.% Al-2%Cr alloys were produced by a powder metallurgy technique followed by hot extrusion. A variety of stable oxides were added to the base alloy to assess the effect of these dopants on the oxidation behavior at 1200°C in air and O2. An Al2O3 dispersion flattened the α-Al2O3 scale, but produced none of the other reactive element effects and had an adverse influence on the long-term oxidation behavior. A Y2O3 dispersion improved the alumina scale adhesion relative to a Zr alloy addition at 1200 and 1300°C. However, the Y2O3 dispersion was not as effective in improving scale adhesion in Fe3Al as it is in FeCrAl. This inferior performance is attributed to a larger amount of interfacial void formation on ODS Fe3Al.

    The effects of excimer laser annealing and yttria on corrosion of an FeCrNi alloy at 700°C (1990)
    Chichester [u.a.] : Wiley-Blackwell
    Surface and Interface Analysis 15 (1990), S. 143-149

    Notes: Several surface and near-surface analysis methods have been used to examine the effects of excimer (KrF, 248 nm) laser annealing and the addition of 2 wt.% Y2O3 on the early stages of corrosion of an Fe-25Cr-20Ni alloy at 700°C. Two specific questions were addressed experimentally: (1) Can excimer laser treatment improve the corrosion properties of the FeCrNi alloy in a mixed gas environment (containing oxygen and sulfur)?; (2) Does the Y2O3-induced improvement of the corrosion behavior of the alloy result from prevention of S segregation to the surface or scale-metal interface? Results show that laser annealing increased the Cr surface concentration of the treated alloy, but did not enhance the formation of a Cr-rich oxide. However, the treated alloy was less susceptible to scale breakdown and sulfide formation. Surface segregation of S was not prevented by the Y2O3 addition. Differences between doped and undoped alloys may be attributable primarily to changes in microstructure.
