    Elastic scattering of α-particles on10B forE α = 5−50 MeV (1976)
    Springer
    The European physical journal 279 (1976), S. 163-168 
    Details
    ISSN: 1434-601X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Experimental data of the elastic scattering ofα-particles on10B forE α = 30−50.6 MeV are presented. They are analysed together with the data of a previous measurement forE α = 5−30 MeV in the frame of the optical model including spin-orbit coupling. The interaction radii of theα-10B-systems are determined with the Inopin-Ericson model forE α = 5−50 MeV. The mean free path ofα-particles in10B is calculated.

    Überlegungen bei der Wahl der Methode zur Analyse von Spurenstoffen (1966)

    Description / Table of Contents: Summary In the determination of materials that are present in very small amounts, it is necessary above all to learn the error of the individual steps of the analysis. The greatest partial error governs the total error of the procedure and usually is due to the inhomogeneity of the material being examined. Only with knowledge of the total error can a decision be reached as to whether the analysis has informational worth, and what apparatus is necessary. The concepts: error, precision, and accuracy are defined and the problem is made clear on the basis of several examples.
    Abstract: Résumé Dans le cas de l'analyse de substances se trouvant en très petites quantités, il est indispensable, en première ligne, d'établir l'erreur intervenant dans chaque étape de l'analyse. L'erreur partielle la plus grande l'emporte sur l'erreur totale du procédé. Elle est due, la plupart du temps, au manque d'homogénéité dû corps étudié. Les notions d'erreur, de précision et d'exactitude se trouvent définies et le problème est rendu explicite à l'aide d'exemples.
    Notes: Zusammenfassung Bei der Analyse von Stoffen, die in sehr geringen Gehalten vorliegen, ist es in erster Linie notwendig, die Fehler der einzelnen Analysenschritte festzustellen. Der größte Teilfehler beherrscht den Gesamtfehler des Verfahrens und ist meist in der Inhomogenität des zu untersuchenden Materials begründet. Erst bei Kenntnis des Gesamtfehlers kann entschieden werden, ob der Analyse Aussagekraft zukommt und welche Apparate notwendig sind. Die Begriffe Fehler, Genauigkeit und Richtigkeit werden definiert und das Problem an Hand einiger Beispiele deutlich gemacht.

    Untersuchungen über das elektrolytisch-potentiostatische Ätzen von nichtrostenden Stählen in 10 n NaOH unter Anwendung eines Coulometers (1969)

    Description / Table of Contents: Investigations into the electrolytic-potentiostatic etching of stainless steels in 10 n NaOH, using a coulometerCurrent density/potential characteristics can only provide qualitative indications concerning the phenomena encountered with potentiostatic etching in 10 n NaOH. The process is best carried out in the trans-passive zone. Identification is based, not on the selective dissolution of certain standard components, but on the interference colours which can be observed as a result of the formation of cover layers of different thickness. The charge density/time characteristics also permit quantitative indications of the different phases. Current density/time curves permit a clarification of the mechanism govering the formation of cover layers. A ferritic steel (28 pC Cr) and a NiCr alloy (45 pC Cr) were found to follow a cubic law of growth, whilst CrNi steel 18-8 is initially governed by an approximately logarithmic law, followed by a zone extending over several hours where the growth begins to follow a parabolic law.
    Notes: Stromdichte-Potential-Kurven ermöglichen nur qualitative Aussagen über die Vorgänge beim potentiostatischen Ätzen in 10 n NaOH. Am günstigsten ist Ätzen im Transpassivbereich. Die Identifizierung erfolgt dabei nicht durch selektive Auflösung bestimmter Gefügebestandteile, sondern aufgrund der Interferenzfarben, die infolge der Bildung unterschiedlich starker Deckschichten zu beobachten sind. Die Ladungsdichte-Zeit-Kurven ermöglichen auch Aussagen über die Mengen der einzelnen Phasen. Stromdichte-Zeit-Kurven ermöglichen eine Aufklärung des Deckschichtbildungsmechanismus. Für einen ferritischen Stahl (28% Cr) und eine NiCr-Legierung mit 45% Cr gilt ein kubisches Wachstumsgesetz, während für CrNi-Stahl 18-8 zunächst ein annähernd logarithmisches Gesetz gilt, an das sich ein mehrstündiger Bereich anschließt, in dem übergang zu einem parabolischen Schichtwachstum erfolgt.

    Ausscheidungs- und Korrosionsverhalten unstabilisierter und stabilisierter 18/10 Chrom-Nickel-Stähle nach kurzzeitigem sensibilisierendem Glühen (1976)
    Weinheim [u.a.] : Wiley-Blackwell

    Description / Table of Contents: Precipitation and corrosion behaviour of unstabilized and stabilized 18 10 CrNi steels after short term sensibilizing annealingThe authors have studied the precipitation behaviour of the steels X5 CrNi 18 9, X10CrNiTi 18 9 and X 10CrNiNb 18 9 after solution and sensibilization annealing, and the intercrystalline corrosion behaviour in the Straußtest. On the basis of the results obtained it was possible to determine the and carbonitrides and to define the grain segregation ranges. In the case of the unstabilized materials the behaviour is a function of the formation of chromium depleted zones. However, it is not absolute value of the depletion at the carbid/austenite interphase which controls corrosion, but the depletion in an adjacent zone of measurable thickness. Beyond that the Huey test allows the corrosion susceptibility to be determined in those regions where no continuous chromium depleted zone exists. In the case of stabilized steels the corrosion behaviour depends in addition from carbonitride precipitation, since these compounds are heavily attacked by the boiling nitride acid.
    Notes: Die Verfasser untersuchten das Ausscheidungsverhalten der Stähle X 5 CrNi 18 9, X 10CrNiTi 18 9 und X 10CrNiNb 18 9 nach Lösungs- und Sensibilisierungsglühen sowie das Verhalten gegen interkristalline Korrosion im Strauß-Versuch. Aufgrund der Ergebnisse konnte die Art der Ausscheidungen bestimmt werden (Karbid M23C6 und Karbonitride) und auch die Kornzerfallsbereiche konnten definiert werden. Im Falle des nichtstabilisierten Materials ist das Verhalten abhängig von der Bildung von chromveramten Zonen; dabei ist jedoch nicht die absolute Höhe der Verarmung an der Grenzfläche Kabid/Austenit ausschlaggebend, sondern vielmehr die Verarmung in einer Zone meßbarer Dicke. Im Huey-Versuch läßt sich außerdem die Korrosionsanfälligkeit in den Zonen ermitteln, wo keine zusammenhängende Chromverarmungszone vorliegt. Im Falle der stabilisierten Stähle ist das Korrosionsverhalten außerdem abhängig von der Karbonitridausscheidung, da diese Ausscheidungen von der siedenden Salpetersäure stark angegriffen werden.
