Effect of neutron irradiation on fracture toughness behaviour of copper alloys

Physical and Mechanical Properties of Copper and Copper Alloys

“…14, [48][49][50] CuCrZr has the highest toughness, and CuNiBe the lowest among these alloys. The large scatter in measured fracture toughness values for CuCrZr in different studies is likely due to different heat treatments, specimen geometry and dimensions, and testing methods.…”

“…The effect of neutron irradiation on fracture toughness has been studied in two alloys, CuCrZr and CuAl25. 14,50,72 Fracture toughness data on neutron-irradiated CuAl25 are available to a dose of 0.3 dpa, and for CuCrZr, the data are available up to 1.5 dpa (Figure 11). Neutron irradiation to 0.3 dpa significantly reduced the fracture toughness of CuAl25 in the temperature range of C. The toughness of irradiated CuAl25 is two to three times lower than that of the unirradiated alloy.…”

Effect of irradiation dose on mechanical properties and fracture character of Cu//SS joints for ITER

“…A weak capability for local deformation usually correlates with a low fracture toughness and the GlidCopAl25 alloy ranks below CuCrZr alloy in fracture toughness as shown by Tathinen et al [12].…”

Thermal stability of heavily drawn Cu–0.4wt.%Cr–0.12wt.%Zr–0.02wt.%Si–0.05wt.%Mg

“…Many researches have focused on the microstructure [5][6][7][8][9], physical properties and mechanical behavior of the alloys [10][11][12][13][14][15][16][17].…”
