Tensile and creep test data of reduced-activation ferritic steel F82H using small specimens and the standard specimen for comparison study

A reduced-activation ferritic/martensitic steel, F82H steel, is the primary candidate structural material for fusion reactor blanket[1]. Tensile and creep test data are essential for blanket design to limit acceptable stress and operation temperature. Especially for fusion materials development, small specimen test technique is required to conserve irradiation volume in high flux neutron field. The present paper reports preliminary results on small and standard size specimens as a summary of the Phase I activity of “Towards the Standardization of Small Specimen Test Techniques for Fusion Applications” under the framework of the International Atomic Energy Agency (IAEA) Coordinated Research Project (CRP-F13017).
