The mechanism of stress influence on swelling of 20% cold-worked 16Cr15Ni2MoTiMnSi steel

Unlimited damage accumulation in metallic materials under cascade-damage conditions

“…[62,[69][70]) has been known for a long time. More recent evidence is due to Kozlov, Portnykh et al [71,72] and Xu et al [73]. In the latter work, association between copper precipitates and vacancy clusters was revealed, which we propose can be due to screening of voids from the SIA clusters by the precipitates.…”

“…In the latter work, association between copper precipitates and vacancy clusters was revealed, which we propose can be due to screening of voids from the SIA clusters by the precipitates. Kozlov, Portnykh et al [71,72] observed spatial correlations in 20% cold-worked 16Cr-15Ni-2Mo-2Mn austenitic steel irradiated up to ~100 dpa irradiation dose in a BN-600 fast reactor in the temperature range from 410 to 600ºC. Transmission electron microscopy revealed voids of three main types: a-type associated with dislocations, b-type associated with G-phase precipitates and c-type distributed homogeneously in the matrix.…”

Radiation Damage Theory

“…35 Experimental evidence on the association of large voids with various precipitates (G, , Laves, etc.) More recent evidence can be attributed to Portnykh et al 165 who studied the microstructure of 20% cold-worked 16Cr-15Ni-2Mo-2Mn austenitic steel irradiated up to $100 dpa in a BN-600 fast reactor in the temperature range from 410 to 600 C. TEM studies revealed voids of three types: a-type associated with dislocations, b-type associated with G-phase precipitates and c-type distributed homogeneously.
