Effect of ITER blanket manufacturing process on the properties of the 316L(N)-IG steel

摘要

Austenitic stainless steel 316L(N)-IG is proposed as one of the base structural materials for the international thermonuclear experimental reactors (ITER) in-vessel components. Various fabrication techniques (hot isostatic pressing (HIP), powder metallurgy, fusion welding and casting etc.) were assessed for the high heat flux components. HIP is the most perspective option because it allows to manufacture components with complicated shape and to Provide joining of heat sink and plasma facing materials, simulaneously, during the same HIP cycle.
