对专用X80钢母材、焊缝及X02/X80热影响区材料在试验堆内进行了辐照,评价特种环境下专用材料的力学性能。辐照累计中子注量(E>1MeV)达到4×10~(16)cm~(-2),辐照温度不高于40℃。对辐照后材料的拉伸性能及冲击性能进行了测试,获得其辐照后的力学性能数据。中子辐照考验在中国原子能科学研究院49-2
The special X80 steel base metal, weld and X02 / X80 heat-affected zone materials were irradiated in the test reactor to evaluate the mechanical properties of special materials in special environment. The cumulative neutron flux (E> 1 MeV) reached 4 × 10 ~ (16) cm -2 and the irradiation temperature was not higher than 40 ℃. Tensile properties and impact properties of the irradiated materials were tested and their mechanical properties after irradiation were obtained.
