    MA956, a commercial ferritic grade of Oxide Dispersion-Strengthened (ODS) steel, was investigated using transmission electron microscopy (TEM) to evaluate the influence of high-temperature thermal cycles on the nanometric dispersed oxides. Analyses of the oxide size distribution were carried out on foils from the as-received MA956 and following treatment at 1285ºC for one hour, and show that growth of the oxides has occurred under the thermal cycle. Implications for the oxide stability in the steel matrix are discussed, in the light of the oxide chemical composition

    Larynx: implants and stents

    Get PDF
    In the human larynx, implants a primarily used for the correction of glottis insufficiency. In a broader sense laryngeal stents may be considered as implants as well. Laryngeal implants can be differentiated into injectable and solid. The most important representatives of both groups are discussed in detail along with the respective technique of application. Laryngeal stents are primarily used perioperatively. Different types and their use are presented

    Entwicklung und Optimierung des Diffusionsschweißens von ODS Legierungen

    Get PDF
    Die Anforderungen an Strukturmaterialien in Generation IV Kernreaktoren steigen durch die Bestrebungen effiziente und umweltverträgliche Reaktoren zu bauen. Oxiddispersionsverfestigte (ODS) Stähle weisen sowohl eine ausgezeichnete Hochtemperaturfestigkeit als auch Bestrahlungsbeständigkeit auf. In dieser Arbeit wird ein Modell zur Vorhersage optimaler Schweißparameter des Festkörperschweißverfahrens Diffusionsschweißen entwickelt und durch eine experimentelle Evaluation optimiert

    Southeast Kansas Climate Summary for 2023

    Temperature and rainfall are important factors influencing agricultural performance. This report summarizes weather conditions in southeast Kansas. Comparisons to long-term records are used to indicate deviations from historical averages. Overall, in 2023 the southeast region had below average precipitation and above normal temperatures
