Changes of structure and properties of yttrium doped copper at deformation, annealing and irradiation

Simulated spatial and temporal dependence of chromium concentration in pure Fe and Fe 14%Cr under high dpa ion irradiation

“…We assume a temperature of 450 ˚C unless otherwise noted. These irradiation conditions are similar to those encountered in the experiments conducted at the Kharkov Institute of Physics and Technology [7,[12][13][14][15]21]. The damage and implanted Cr profiles were calculated using the Kinchin-Pease option in SRIM-2013 [24,25].…”

“…In this study we have chosen to model irradiations using 1.8 MeV Cr + ions because a large number of experimental studies have been conducted at the Kharkov Institute of Physics and Technology in the Ukraine on a wide variety of austenitic, ferritic, ferriticmartensitic and oxide-dispersion-strengthened ferritic alloys, exploring doses of 50-600 dpa at a dpa rate of 1-2 x10 -2 dpa/sec [7,[12][13][14][15].…”

“…There has been a significant body of experimental work on RIS in ion irradiated Fe-Cr based alloys (e.g., [7,[12][13][14][15][18][19][20][21]) but it not clear from these works what happens to implanted ions in the entire damage region, particularly at very high doses where the implanted ions can significantly change composition. In general, it is not understood how the injected interstitials impact local alloy composition and RIS in the damage region.…”

Thermal conductivity and diffusivity of Cu-Y alloys produced by different powder metallurgy routes

“…Previous studies have reported that in ODS Cu-Y 2 O 3 , the dispersion of Y 2 O 3 nanoparticles gives place to an increase in the mechanical resistance of copper [6,7]. Furthermore, Neklyudov et al have reported that the presence of a small amount of yttrium dispersed in copper reduces the damage of defects due to neutron irradiation [8].…”
