Untersuchungen über die Bestimmung der Zähigkeit von Bauteilen im Apparatebau durch Messungen an Modellbehältern von praxisähnlicher Größe. Versuche mit Behältern aus Kesselblech H 1 bei Temperaturen −80°C

Research into the Determination of the Ductility of Structural Elements in Plant Construction by Measurement on Model Vessels of Near Industrial Size— Tests on Boiler Plate Vessels (Kesselblech H 1) at Temperatures Down to ?80°C The paper deals with a research program of the Dechema working group “Materials for Chemical Apparatus”, by which an attempt is made to correlate ductility as a characteristic materials property with ductility changes to be expected in structural elements and structures. On a low temperature test stand model containers are loaded internally until bursting and the deformations of a container bottom having a complex shape are measured. Deformation and bursting pressure vs. temperature support the preliminary conclusion that the embrittlement temperature for such structures is lower than the notch toughness transition temperature of the material. Corroboration of this finding requires further work with other materials and structures.
