Description

Small angle neutron scattering is used as an effective method of detecting structural changes during non-destructive determination of the remnant life of heavily loaded components. Small angle neutron scattering (SANS) measurement permits a direct and quantitative determination of the parameters which are essential for the high-temperature creep strength of a material. From the connection between the SANS signal and creep strain, conclusions can be derived for remnant life. (orig.)

Abstract (German)

Die Neutronen-Kleinwinkelstreuung wird als empfindliche Methode zum Nachweis von Gefuegeaenderungen bei der zerstoerungsfreien Ermittlung der Restlebensdauer von hochbelasteten Komponenten eingesetzt. Die Small-Angle-Neutron-Scattering-(SANS-)Messung erlaubt eine direkte und quantitative Bestimmung der fuer die Hochtemperatur-Kriechfestigkeit eines Materials wesentlichen Kennwerte. Aus dem Zusammenhang zwischen SANS-Signal und Kriechdehnung lassen sich Aussagen ueber die Restlebensdauer ableiten. (orig.)
