Es konnte festgestellt werden, daß ein Werkstoff der vorgeschlagenen Art durch Dispersion fester Oxide der genannten Art im Hechtemperaturbereich von Schnellneutronenreaktoren Werte for Langzeit-Kriecheigenschaften ausweislieh die denen eines Stahles der Qualität AlSI 316, der als Bezugsqualität dient, überlegen sind. Auch bei Bestrahlung durch schnelle Neutronen in Flußdichten über lO^n/cm2 kommt es praktisch zu keinerlei Versprödung oder Aufblähung.Make opportunities. It was found that a material of the proposed type through dispersion of solid oxides of the type mentioned in the high temperature range of high-speed neutron reactors shows values for long-term creep properties that are superior to those of a steel of the quality AlSI 316, which is used as a reference quality. Even when irradiated by fast neutrons in flux densities above 10 ^ n / cm 2 , there is practically no embrittlement or bloating.
Gleichfalls verursacht die dynamische Natriumkorrosion keinerlei einschneidende Veränderungen des vorstehend definierten Werkstoffes.Likewise, dynamic sodium corrosion does not cause any drastic changes in the material defined above.
