    Notes: Abstract Different sources of error in determining surface tension by the sessile drop technique are discussed. The influence of uncertainties in measuring drop co-ordinates are quantitatively evaluated, and the results tested on Ag and Pb drops at different temperatures. Shifts in surface tension values, due to errors in determining the exact scale factor and to errors in reading temperature or density, are calculated, and a nomographic chart, to find the optimum drop weight, is also presented.

    Notes: Abstract The surface tension of liquid tin has been measured by the sessile-drop technique as a function of temperature, in the range 232 ⩽T (°C) ⩽ 800 and under different atmospheres. It is shown that oxygen strongly affects the surface tension values and that, under “nominally” very clean conditions, a considerable scatter of experimental results occurs. This scatter can be explained by taking into account kinetic factors, especially those related to the gaseous fluxes around the molten drop. By this procedure, a number of experimental results can be singled out, which corresponds to “clean” surface conditions. On the basis of these results, the following expression for surface tension politherm is proposed: σ(mN m−1 = 581-0.13) (t-232).

    Notes: Abstract The behaviour of several types of silicon nitride-based materials in contact with molten copper has been evaluated. Tests were performed at a temperature of 1400 K for a holding time of 260 h in fluido-dynamic conditions. The extent of corrosion has been evaluated in terms of linear loss, weight loss, morphology and chemical composition of the surfaces remaining in contact with the molten phase, by means of SEM, EPMA and X-ray diffraction. Corrosion resistance has been found to be a function of the chemical composition, type and amount of the secondary phases. Materials produced with MgO as a sintering aid showed poor resistance whereas those with Al2O3 exhibited the best performance. In any case the extent of corrosion was very slight and the results revealed that all the tested ceramics may be considered suitable for use in contact with molten copper.

    Description / Table of Contents: Schwingungskorrosionsverhalten von Armco-Eisen als Funktion der WärmebehandlungDie Autoren haben ein Prüfgerät für Schwingungskorrosion entwickelt, das auf einfache Weise vielen Anforderungen bei dieser spezifischen Prüfung entspricht. Im einzelnen kann die Zeitabhängigkeit des Spannung-Dehnung-Verhaltens für jeden Punkt der Probe ermittelt werden, die Belastung kann verändert und geregelt werden, auch elektrochemische Messungen lassen sich leicht durchführen und schließlich wird auch hohe Reproduzierbarkeit erreicht. Die Probe wird dabei als Hebelprobe eingesetzt. Die in der Arbeit vorgelegten Ergebnisse betreffen die Veränderungen im Gefüge von Armco-Eisen im Anschluß an zwei Wärmebehandlungsarten, und zwar A. Erhitzen im Vakuumofen auf 760°C, 2 h Haltezeit, Abschrecken in Wasser auf 20°C (in einigen Fällen wurde auch Natriumchloridlösung oder eine wässerige Ölemulsion verwendet)B. Erhitzen im Vakuumofen auf 760°C, eine Stunde Haltezeit, dann auf 925°C, 4 h Haltezeit, Abschrecken wie unter (A).Im Anschluß an diese beiden Wärmebehandlungen ist Sensibilisierung bzw. Unempfindlichkeit gegen interkristalline Korrosion und da mit auch gegen Schwingungsrißkorrosion festzustellen.
    Notes: A corrosion fatigue testing device is presented which satisfies in a simple way many needs of this kind of research. In particular, the behaviour of stresses and strains vs. time is known at every point of the specimen; load may be varied and controlled; electrochemical measures are easily obtained; reproducibility is assured. The specimen acts as a cantilever beam. Results are presented and discussed concerning alterations in the structure of Armco iron as a consequence of the following two heat treatments: A. heating in a vacuum furnace at 760°C for two hours, quenching in water (some experiments have been performed quenching in NaCl solution or in aqueous oil emulsion) at 20 °C.B. heating in a vacuum furnace at 760°C for one hour, then at 925°C for four hours, quenching under the same conditions as in A.Sensitization and protection with respect to intergranular attack and consequently to the rate of fatigue corrosion cracking respectively follow the two above mentioned heat treatments.
