摘要

To investigate the irradiation effects on CLAM, neutron irradiation experiments are being carried out under wide collaboration in China and overseas. In this paper, the effects of low fluence neutron irradiation on mechanical properties of CLAM were analyzed. The mechanical properties of CLAM heats 0603A, 0408B and 0408D had been tested before and after neutron irradiation to 0.02dpa. The specimens were irradiated at 250℃ to a fast neutron fluence of 1.51×10<'19>n/cm<'2> (E>IMeV). The test results showed that ultimate strength and yield stress of them increased about 10MPa and ductile to brittle transition temperature (DBTT) increased about 5℃. In addition, irradiation effects on CLAM and other RAFMs under similar irradiation conditions were introduced and compared.
