Strategies to lower the DBTT of RAFM steels acting on chemical composition and thermomechanical treatments

Nuclear Materials and Energy
ENEA and its industrial partner Rina Consulting-CSM (RINA CSM) contribute to the Eurofusion programme in the development of innovative RAFM steels able to withstand the critical low temperature (280-300 °C in the “water-cooling” option) foreseen for the ...

Probing the interplay among elevated-temperature mechanical properties, microstructural evolution, and dynamic strain aging in reduced activation ferritic/martensitic steels

Journal of Materials Research and Technology
The effects of temperature (room temperature, 350 °C, 550 °C) on the microstructure evolution and mechanical properties of reduced activation ferritic/martensite steel (RAFM) were investigated using tensile experiments and theoretical calculations.

Quantifying helium-bubble swelling in RAFM steels using TEM and the surface-step method

Nuclear Materials and Energy
In fusion-relevant environments where transmutation helium accumulates, He bubble formation can become a critical damage mechanism in reduced-activation ferritic/martensitic (RAFM) steels because it drives swelling and can degrade mechanical performance.

Microstructure and thermal stability of a structurally graded tungsten and reduced activation ferritic/martensitic steel joint

Journal of Materials Research and Technology
The leading design for plasma-facing high heat flux components in proposed fusion reactors involves joining plasma-facing tungsten tiles to underlying reduced activation ferritic-martensitic (RAFM) steel structures.

Irradiation Effects on Tensile Properties of Reduced Activation Ferritic/Martensitic Steel: A Micromechanical-Damage-Model-Based Numerical Investigation

Crystals
The tensile properties of reduced activation ferritic/martensitic (RAFM) steels are significantly influenced by neutron irradiation. Here, a mechanism-based model taking account of the typical ductile damage process of void nucleation, growth, and ...
