    Description / Table of Contents: Investigations into oxidation and mechanical properties of aluminium cast iron at temperatures of 923 to 1373 KAn analysis of the oxidation process of aluminium cast iron containing up to 30% Al has been made and tests of the mechanical properties of cast iron have been carried out at different temperatures (923-1373 K). The oxidation process was carried out in air of 1 bar pressure. Measurements of kinetics were made using the gravimetric method in the above temperature range. The oxidation products were identified by x-ray microanalysis, x-ray diffraction and metallographic analysis. The mass change during the oxidation process was evaluated in cycling temperature conditions. Mechanical properties were determined and involved hardness, impact resistance and abrasion behaviour. The corrosion resistance was defined as well as the change of mechanical properties of the cast iron at higher temperatures.
    Notes: Es wurde die Oxidation von Aluminiumgußeisen analysiert und die mechanischen Eigenschaften des Gußeisens im Temperaturbereich 923-1373 K geprüft. Die Oxidation wurde in Luft bei einem Druck von 1 bar durchgeführt, die Kinetik wurde gravimetrisch ermittelt. Die Analyse der Oxidationsprodukte erfolgte durch Mikrosonden- und Röntgenfeinstrukturuntersuchungen. Ebenfalls verfolgt wurde Massenänderung während des Oxidationsprozesses bei periodisch wechselnder Temperatur. An mechanischen Eigenschaften wurden Härte, Schlagfestigkeit und Verschleißverhalten untersucht. Ziele der Versuche waren die Bestimmung der Korrosionsbeständigkeit sowie die Veränderungen der mechanischen Eigenschaften unter Wärmeeinwirkung.

    Description: The oxidation process of two-component Fe-Al alloys containing up to 7.2% Al and from 18 to 30% Al was studied. Kinetic measurements were conducted using the isothermal gravimetric method in the range of 1073-1223 K and 1073-1373 K for 50 hours. The methods used in studies of the mechanism of oxidation included: X-ray microanalysis, X-ray structural analysis, metallographic analysis and marker tests.
