One of the main challenges for some reactors components in austenitic stainless steels at high temperature in-service conditions is the demonstration of their behavior up to 60 years. The creep lifetimes of these stainless steels require on the one h

Because of their good thermo-physical properties, 9Cr steels are being considered as structural materials for fusion and fourth generation nuclear reactor components. However, these materials feature a particular behaviour in strain hardening, they p

Different batches of austenitic stainless steels (316LN) are subjected to numerous creep tests carried out at various stresses and temperatures between 525 °C to 750 °C up to nearly 50•103h. Interrupted creep tests show an acceleration of the cre
