摘要：

Swelling of austenitic stainless steels. Austenitic stainless steels are widely used in the core of the nuclear reactors and are thus subject to significant neutron flux, leading to strong evolutions of their properties. One of most significant is swelling (isotropic volume expansion). This deformation induced by the irradiation is due to the void formation. Swelling is a threshold phenomenon that depends on the irradiation conditions, temperature and flux, but also on the metallurgical state and its chemical composition. The change of steels, from SA 316 to CW 15-15 Ti, has increased by a factor 3 the lifetime of Sodium Fast Reactor subassemblies.
