Thermal creep behaviour of the EUROFER 97 RAFM steel and two European ODS EUROFER 97 steels
Fusion Engineering and Design, 2005 Thermal creep tests have been conducted on the EUROFER 97 reduced activation ferritic/martensitic (RAFM) steel and two kinds of oxide dispersion strengthened (ODS) EUROFER 97 steels, which were manufactured using slightly different powder metallurgy techniques at the Centre of Research in Plasma Physics, Switzerland and at the CEA Grenoble, France ...

Study the erosion of RAFM steels with the linear plasma device GyM [PDF]
, 2021 The use of bare reduced activation ferritic martensitic (RAFM) steels, like Eurofer-97, has recently been envisaged as a possible option for the recessed elements of the first-wall of DEMO. The erosion by hydrogenic charge-exchange neutrals (CXNs) can significantly affect the lifetime of these components and needs to be assessed properly [1].

Fusion Engineering and Design, 2019
Abstract The comparative study of high temperature deformation behaviour of P91, RAFM-CLAM and Low C RAFM-CLAM steels was done from compression deformation data in the temperature range of 850–1100 °C and the strain rate range of 10−3–10 s-1. The processing maps in terms of strain rate sensitivity (m), % efficiency of power dissipation (ƞ) and the ...
