摘要

Abstract

The mechanical performance and morphology of zirconium hydrides, as well as the dislocation structure and characteristics of phase precipitates in the E635 alloy-made cladding of fuel elements and guide channels used in VVER-1000 fuel element assambly, have been studied. It has been found that postradiation thermal treatment has an influence on the mechanical performance of these products, which shows up as a change in microstructure properties and element redistribution between the solid solution and phase precipitates.
