Tensile, low cycle fatigue and fracture toughness behavior of type 316L irradiated to 0.3 dpa

The effect of a low dose neutron irradiation on the tensile, low cycle fatigue and fracture toughness properties of type 316L steel plate and weld material was investigated. The specimens were irradiated at a temperature of approx35 deg C to a neutron fluence of approx2.5x10 exp 20 n/cm exp 2 (E >...

Description
Summary:The effect of a low dose neutron irradiation on the tensile, low cycle fatigue and fracture toughness properties of type 316L steel plate and weld material was investigated. The specimens were irradiated at a temperature of approx35 deg C to a neutron fluence of approx2.5x10 exp 20 n/cm exp 2 (E > 1 MeV). The testing was performed at 75, 250 and 450 deg C. Irradiated tensile specimens showed a substantial radiation hardening combined with some reduction of elongations. There was no significant effect of the irradiation on the low cycle fatigue endurances. The fracture toughness of the TIG weld specimens was roughly half of that of the 316L plate and electron beam weld. Some reductions of toughness owing to the irradiation were observed.
