主 题：Accident-tolerant fuel cladding FeCrAl Laves phase In-situ radiation Segregation
摘 要：As a promising candidate material for the accident tolerant fuel cladding in light water reactors,the Nb-containing FeCrAl alloy has shown outstanding out-of-pile service performance due to the Laves phase *** this work,the radiation response in FeCrAl alloys with gradient Nb content under heavy ion radiation has been *** focus is on the effect of the Laves phase on irradiation-induced defects and *** found that the phase boundary between the matrix and Laves phase can play a critical role in capturing radiation defects,as verified by in-situ heavy-ion radiation experiments and molecular dynamic ***,the evolution of Laves phase under radiation is ***-induced amorphization and segregations observed at high radiation doses will deepen the fundamental understanding of the stability of Laves phases in the radiation environment.
