Influence of Aging on the Fracture Toughness of Cryogenic Austenitic Materials, Evaluated by a Simple Test Method

Part of the Advances in Cryogenic Engineering book series (ACRE, volume 38)


The fracture toughness of heat treated austenitic stainless steel is measured. The data collected using a simple dynamic bend test at 77 K are compared and scaled with values measured on CT specimens at 4 K. It shows that the toughness depends strongly on the temperature and time of the heat treatment and that — as long as there is no need for values according to certain standards — expensive and time consuming 4 K tests on CT specimens can be substituted. The data are presented in three dimensional graphs.
