    Description / Table of Contents: Corrosion fatigue behaviour of steel Ck 45 in aqueous solutions containing chloride ionsThe fatigue behaviour of carbon steel Ck 45 (comparable to AISI 1045x) is investigated for cyclic tension and rotating bending load with a frequency of 25 Hz. The fatigue limits under cyclic tension load in air are 410 N/mm2 for smooth specimens and 290 N/mm2 for notched specimens. For rotating bending load a value of 200 N/mm2 is found for smooth specimen.The fatigue limits for N = 107 in two different environments (0.3% and 3% NaCl-solution) reach only 37-57% of the according values in air. Cathodic protection of smooth specimens causes an improvement to 95% of the air fatigue limit.The evaluation of the free corrosion potential for all corrosion fatigue tests and the appearence of fracture show typical attributes of corrosion fatigue in the active state.
    Notes: Am Beispiel des unlegierten Stahles Ck 45 wird in NaCl-Lösung das Schwingungsrißkorrosionsverhalten im aktiven Zustand durch Variation der Probengeometrie, der Belastungsart, der Elektrolytkonzentration und der Prüfftemperatur eingehend untersucht. Alle Dauerschwingversuche werden dabei mit einer Prüffrequenz von 25 Hz bis zu einer Grenzschwingspielzahl von 107 durchgeführt.Gegenüber den Vergleichsversuchen an Luft sinkt durch den gleichzeitigen Korrosionsangriff die Zeitschwingfestigkeit sehr stark ab, wobei der Festigkeitsverlust abhängig von den Versuchsparametern zwischen 43% und 63% beträgt. Die Vorgabe eines geeigneten elektrochemischen Potentials bewirkt eine deutliche Erhöhung der Korrosionszeitschwingfestigkeit auf 95% der Luftdauerfestigkeit.Die bei allen Versuchen durchgeführten elektrochemischen Messungen sowie die fraktographischen Untersuchungen zeigen die für SwRK im aktiven Zustand typischen Erscheinungen, die auf die gegenseitige Steigerung der mechanischen Beanspruchung und des Korrosionsangriffs zurückzuführen sind.

    Notes: Reactions in distillation columns. Reaction columns are an interesting alternative for numerous reactions, and they have often proved economically advantageous. The effects resulting from superposition of reaction and distillation are demonstrated for a few examples and the industrial exploitation of such a system is illustrated. In comparison to the processes in actual distillation columns the processes in reaction columns are extremely complex. It is therefore advantageous in industrial engineering design to have suitable mathematical models at hand. Control problems can be overcome by profile control or by dynamic detectors.
