摘要：

Subsized Charpy V-notch (1/4-CNV and 1/3-CVN) impact properties of A533B steel have been investigated after neutron irradiations at 290degreesC. Irradiations were performed under six different conditions of neutron flux-fluence combinations utilizing a well established temperature/fluence controlling technique in JMTR. A general tendency that lower flux irradiation causes larger DBTT shift has been clearly observed. Especially the 1/3-CVN irradiated to 1.6-1.9x10(22) n/m(2) showed large flux dependence. DBTT shifted by only 4degreesC for the higher flux while by about 28degreesC for the lower flux. The difference was also evident in temperature dependence of dynamic yield load in load-displacement curves from the impact tests. Greater temperature dependence of the dynamic load was a characteristic for the lower flux irradiations.
