Journal ArticleDOI
Ion irradiation combined with nanoindentation as a screening test procedure for irradiation hardening
TL;DR: In this paper, a combination of ion irradiation and nanoindentation was used to establish a screening test procedure for the resistance of ferritic/martensitic (f/m) steels to neutron damage in terms of hardening.
Journal ArticleDOI
On the estimation of ultimate tensile stress from small punch testing
Eberhard Altstadt,M. Houska,Igor Simonovski,Matthias Bruchhausen,Stefan Holmström,Roberto Lacalle +5 more
TL;DR: In this article, the authors used finite element simulations of the small punch test to evaluate and improve empirical correlations for the estimation of the ultimate tensile stress from force-deflection and force-displacement curves.
Journal ArticleDOI
Critical evaluation of the small punch test as a screening procedure for mechanical properties
Eberhard Altstadt,H.E. Ge,V. Kuksenko,Marta Serrano,M. Houska,M. Lasan,Matthias Bruchhausen,J.-M. Lapetite,Y. Dai +8 more
TL;DR: In this article, a systematic and statistically based analysis of the repeatability and device dependence of small punch test results was performed on an unirradiated ferritic-martensitic steel T91.
Journal ArticleDOI
Contributions of Cu-rich clusters, dislocation loops and nanovoids to the irradiation-induced hardening of Cu-bearing low-Ni reactor pressure vessel steels
Frank Bergner,F. Gillemot,M. Hernández-Mayoral,Marta Serrano,Gyula Török,A. Ulbricht,Eberhard Altstadt +6 more
TL;DR: In this article, a set of Cu-bearing low-Ni RPV steels and model alloys was characterized by means of SANS and TEM in order to specify mean size and number density of loops, nanovoids and CRPs.
Proceedings ArticleDOI
European Standard on Small Punch Testing of Metallic Materials
Matthias Bruchhausen,Tim Austin,Stefan Holmström,Eberhard Altstadt,Petr Dymáček,Spencer Jeffs,Robert Lancaster,Roberto Lacalle,Karel Matocha,Jana Petzová +9 more
TL;DR: In this paper, the current status of the standard and highlights some of the changes with regard to the current CWA 15672 (2007) standard is described, as well as a machine readable format for representing and transferring test data.
