Dans le cadre du développement de matériaux de gainage combustible pour les réacteurs à neutrons rapides refroidis au sodium (RNR-Na), cette étude s’intéresse au développement d’un procédé innovant d’élaboration d’aciers renforcés par dispersion d’oxyde (aciers ODS) par mécanosynthèse qui doit éviter l’apparition de précipités de tailles micrométriques indésirables dont la présence dégrade drastiquement les propriétés mécaniques. Ce nouveau procédé consiste à introduire directement des nanoparticules d’oxydes de structure pyrochlore Y2Ti2O7 dans une poudre métallique Fe-Cr via un broyage. Pour cela, un procédé de synthèse des oxydes de structure pyrochlore Y2Ti2O7 par co-broyage des poudres nanométriques Y2O3 et TiO2 a d’abord été mis en pl...
