COMPARISON OF EXPERIMENTAL TECHNIQUES FOR MEASURING FRACTURE TOUGHNESS OF AUSTENITIC STAINLESS STEELS BY PERFORMANCE OF A COMPARATIVE ROUND-ROBIN TEST
For the Activity Group 3 "Materials' of the Working Group for Codes and Standards within the CEC Fast Reactor Coordinating Committee a round robin-test programme on 316 L mod. stainless steel has been performed aimed at comparing experimental techniques and assisting in establishing a standard test method for these steels. In this report the J-DELTAa-curves measured by the seven participating laboratories are compared, a common J-DELTAa- curve is established from the multi-specimen-technique and the results from the unloading compliance-, potential drop- and crack tip opening displacement-techniques are discussed. Conclusions and recommendations have been drawn concerning the evaluation of J-DELTAa-curves of austenitic stainless steels and the necessary requirements for the different test techniques.
