    Notes: Abstract The anodic polarization of zircaloy-2 in different electrolytic baths has been investigated in order to obtain thick oxide films with properties suitable for wear applications. The operative conditions to obtain hard, thick, compact oxide films resistant to thermal shocks have been determined. The influence of the bath composition and temperature on the oxide growth is reported.

    Description / Table of Contents: Untersuchung der interkristallinen Korrosion von Alloy 800 mit Hilfe der elektrochemischen potentiokinetischen ReaktivierungsmethodeDie elektrochemische potentiokinetische Reaktivierungsmethode wurde benutzt, um das Ausmaß der interkristallinen Korrosion von Alloy 800 (unterschiedliche Gehalte an Ti+Al, Wärmebehandlung bei 500-650°C, Wärmebehandlungsdauer bis 500 Stunden) quantitativ zu ermitteln. Die Ergebnisse wurden mit den klassischen Rollason Kurven verglichen, die mit dem Strauß-Test ermittelt wurden; dabei ergab sich befriedigende Übereinstimmung.Um die geringfügigen Unterschiede zwischen den nach beiden Methoden erhaltenen Ergebnissen zu erklären, wird die Morphologie des Passivierungsfilms herangezogen.
    Notes: The “Electrochemical Potentiokinetic Reactivation” method has been employed to quantify the degree of intergranular corrosion of Alloy 800, with different Ti + Al content, aged in the range 500-650°C for times up to 5000 hours. The results were compared with the classical Rollason's curves obtained by means of the Strauss' test and a satisfactory agreement was found.An explanation of the slight differences between both methods has been proposed on the basis of the passivity film morphology.

    Description / Table of Contents: Stress corrosion cracking of Inconel 600 tubing: Influence of thermal treatment, NaOH concentration and temperatureA study has been performed concerning the role of thermal treatments on the SCC behaviour of Inconel 600 tubing in NaOH solutions in the temperature range 315-360°C. An additional investigation was undertaken to establish the effect of the NaOH concentration built-up under magnetite deposits. The changes in the microstructural variables in the four metallurgical conditions studied were indentified by transmission electron microscopy (TEM). C-ring and slow strain rate tests (10-6s-1) yielded identical results. SEM fractographs were additionally taken to reveal the cracking mode. It has been found that thermal treatment improves the SCC resistance in hot caustic solutions; particularly annealing at 650°C for 50 h appeared to impart the maximum improvement of SCC resistance.
    Notes: Eine Unterschung über den Einfluß der Wärmebehandlung auf das SpRK-Verhalten von Rohren aus Inconel 600 in NaOH-Lösungen bei 315 bis 360°C wurde ergänzt durch Untersuchungen über den Einfluß der NaOH-Anreicherung unter Magnetitschichten; die dabei auftretenden Gefügeänderungen wurden mittels TEM nachgewiesen. Versuche mit C-Ringen und mit langsamer Dehnung (slow strain rate, SSR) bei 10-6s-1 Dehngeschwindigkeit führten zu den gleichen Ergebnissen; REM-Untersuchungen wurden zur Beurteilung der Bruchflächen ausgeführt. Dabei zeigte sich, daß Wärmebehandlung die Anfälligkeit für SpRK in Natronlauge bei hohen Temperaturen vermindert; insbesondere scheint die Wärmebehandlung bei 650°C/50h das SpRK-Verhalten besonders wirkungsvoll zu verbessern.
