Void swelling in copper and copper alloys irradiated with fission neutrons

Radiation Damage Theory

“…These include the void lattice formation [11][12][13][14] and higher swelling rates near GBs than in the grain interior in the following cases: high-purity copper and aluminum irradiated with fission neutrons or 600 MeV protons (see original references in reviews 117,118 ); aluminum irradiated with 225 MeV electrons 119 and neutron-irradiated nickel 120 and stainless steel. 32,33 And, although generally the bcc materials show remarkable resistance to swelling, 31,33 the alloy V-5% Fe showed the highest swelling rate of $2% per dpa: 90% at 30 dpa. It gradually became clear that something important was missing in the theory.…”

Nanostructural Evolution of Cr-rich Precipitates in a Cu-Cr-Zr Alloy During Heat Treatment Studied by 3 Dimensional Atom Probe

“…For example, it has been found that higher content of Cr results in the formation of coarser Cr precipitates which improves the radiation resistance. 10) The specimens were prepared from tensile test specimens. The tensile test specimens were heated in a furnace at a vacuum of less than 1 mPa (10 À5 torr) and then water quenched.…”

Physical and Mechanical Properties of Copper and Copper Alloys

“…[78][79][80][81][82] A study by Witzig 82 showed no enhancement of creep rates in copper relative to thermal creep at 260 C and 69 MPa under light ion irradiation. Jung 79 studied irradiation creep of 20% cold-worked copper foils at temperatures of C and the applied tensile stress of 20-70 MPa under 6.2 MeV proton irradiation with displacement rates of 0.7-3.5 Â 10 -6 dpa s À1 .…”
