Abstract

Austenitic stainless steels, in which nickel is partly or completely substituted by manganese accompanied by an addition of nitrogen, have been studied at JRC Ispra. The work carried out so far was aimed at characterizing Cr-Mn steels with respect to many properties relevant for a fusion environment, in order to assess the possible use of these steels as candidate materials for fusion reactors. This review includes results obtained on structural changes due to thermal treatment with and without plastic deformation. The mechanical behaviour, in a broad range of temperature, is also discussed as a function of different mechanical treatments (cold working). Furthermore, irradiation effects, swelling and phase stability, obtained by electron irradiations, are presented. The influence of lithium on corrosion, structural stability, intergranular penetration and tensile properties is described. Finally, the neutronic performances of Cr-Mn steels are given with attention to radiation damage properties, composition changes, decay heat, induced radioactivity and effect on tritium breeding.
