Abstract

Abstract

The investigation was conducted on two plates of recrystallized new N18 zirconium alloy i.e N18-1（T-L） and N18-2（L-T）, which are with the same chemistry composition but different texture. In order to study the property of iodine-induced stress corrosion crack of the zirconium alloy plates, the tests were carried out in different test conditions, and dynamic monitor was used to measure the length of stress corrosion crack. The texture, the second phase particles and fractographs were also investigated. Result shows that N18-2 （L-T） has better I-SCC resistance than N18-1（T-L） at the two set of test conditions. In addition, SEM observation shows that the cracks are mainly trans-granular and pseudo-cleavage, but at the first stage, the crack is inter-granular.
