    Description / Table of Contents: Verhalten von ferritischem Stahl Irn ML-1 NatriumkorrosionskreislaufDer ferritische Stahl AISI 430 wurde 6000 h bei 500 und 570 °C im ML-1 Natriumkreislauf ausgelagert. Die Proben wurden zur Auswertung der Korrosions- und Ablagerungseffekte nachuntersucht. Zusätzlich zu den Gewichtsänderungsmessungen und metallographischen Techniken wurden Oberflächenanalysen mit der Glimmentladungsspektrometrie und der AUGER-Elektronenspektrometrie sowie das Rasterelektronenmikroskop mit Röntgen-Analyse herangezogen.Korrosion und Ablagerung beeinflußten etwa 0,01 mm dünne Schichten, die Gewichtsverluste waren denen der austenitischen Stähle vergleichbar. Der Stahl wurde durch Natrium nicht entkohlt. Auf den Oberflächen hatten sich Sauerstoff enthaltende Verbindungen gebildet. In der Zone der Abströmung wurden auch metallische Ablagerungen, die an Nickel reich waren, beobachtet.
    Notes: The ferritic steel AISI 430 has been exposed up to 6000 hours at 500 and 570 °C in the ML-1 sodium loop. The specimens were examined to evaluate the corrosion and mass transfer phenomena. Additional to weight change measurements and metallographic techniques surface layer analyses by Glow Discharge Optical Spectrometry and AUGER Electron Spectrometry and also scanning electron microscopy with Xray analysis were applied.Corrosion and deposition influenced about 0.01 mm thin layers, weight losses were comparable to those of austenitic steels. The steel was not decarburized by the sodium. On the surfaces oxygen containing compounds have formed. In the down-stream area also metallic deposits rich in nickel were observed.

    Notes: Thiazoles substituted in positions 2 and 4 by hydroxy, mercapto and amino groups were synthesized, as well as its carbamate derivates and formylhydrazones. The research of the reaction of the formylhydrazide with 4-imino-2-thiazolidinone has not given the pyrazolo [3,4-d]- thiazol-2-one, but the 4-formylhydrazono-2-thiazolidine. The detailed tautomeric study of each of the heterocyclic compounds has been carried out by infrared spectroscopy, nuclear magnetic resonance of proton and of 13-carbon, and of masses.
