Fast neutron irradiation of alloys with a higher nickel content than SS 316
Description
Previous tests have shown the importance of nickel in the swelling of iron-nickel-chromium alloys. Results of irradiation by fast neutrons of alloy richer in nickel than stainless steels are reported. Main conclusions are: hardened austenitic steels with a Ni content of 20 and 25% are not better than 316 because of high deformation for low stress; swelling and creep irradiation are lower than for 316 (Ti) in alloys NIM PE 16, INC 706 or INC 625 irradiated under 5000C and 75 dpa F; with Inconel 706 ductility still good at room temperature or at 4500C is very low at 6000C

Des experiences ont montre le role important du nickel dans le gonflement d'alliages fer, chrome, nickel. Aussi on a procede a l'irradiation par les neutrons rapides d'alliages plus riches en nickel que l'acier 316. Les conclusions principales montrent que: les aciers austenitiques hypertrempes a 20 et 25% de nickel ne sont pas meilleurs que le 316 a cause de leur forte deformation sous faible contrainte; les alliages NIM PE 16, INC 706 ou 625 gonflent moins que le 316 (Ti) irradies dans les memes conditions t < 5000C et 75 dpaF et le fluage d'irradiation est plus faible; la ductilite de l'inconel 706 montre que la ductilite a la temperature ambiante et a 4500C conserve une valeur raisonnable mais est pratiquement nulle a 6000CFiles
