TL;DR: In this paper, the effect of helium (He) on tensile properties and microstructure of oxide dispersion strengthened EUROFER-ODS steel, flat tensile specimens were homogeneously implanted with 30 MeV α-particles at the NRC KI cyclotron up to 1000 amm He at 573 K and 773 K.
26 citations
TL;DR: In this article, a complex study of structural state and properties of 18Cr-10Ni-Ti austenitic stainless steel after irradiation in BOR-60 fast research reactor (in the temperature range 330-400° up to damaging doses of 145-dpa) and in VVER-1000 light water reactor (at temperature ∼320-°С and damaging doses ∼12-14 dpa) was performed and the possibility of recovery of structural phase state and mechanical properties to the level almost corresponding to the initial state by the recovery annealing was studied.

TL;DR: In this paper, a wide range of pressure vessel steels were studied using microstructural and fractographic methods, in the initial state (i.e., unirradiated), after irradiation, recovery annealing and re-irradiation, and the analysis of the data has allowed quality explanations of the key features of radiation embrittlement (RE) in RPVS, and also to justify the existing concepts concerning the mechanisms of RE.

TL;DR: In this article, the authors present the current understanding of the selective removal of atoms (SRA), a technique that uses ion irradiation to controllably change the chemical composition and properties of polyatomic materials.
Abstract: This paper reviews the current understanding of the selective removal of atoms (SRA), a technique that uses ion irradiation to controllably change the chemical composition and properties of polyatomic materials. The main effects involved and the possible mechanisms that govern the process are discussed. It is shown that SRA holds great promise for manufacturing functional nanoelements.

TL;DR: Using confocal Raman and fluorescence spectroscopic imaging in 3-dimensions, this paper showed direct evidence for Nd3+-Nd3+) interactions across grain boundaries (GBs) in Nd 3+:YAG laser ceramics.
Abstract: Using confocal Raman and fluorescence spectroscopic imaging in 3-dimensions, we show direct evidence for Nd3+-Nd3+ interactions across grain boundaries (GBs) in Nd3+:YAG laser ceramics. It is clearly shown that Nd3+ segregation takes place at GBs leading to self-fluorescence quenching which affects a volume fraction as high as 20%. In addition, we show a clear trend of increasing spatial inhomogeneities in Nd3+ concentration when the doping levels exceeds 3 at%, which is not detected by standard spectrometry techniques. These results could point the way to further improvements in what is already an impressive class of ceramic laser materials.
