Effect of self-ion irradiation on hardening and microstructure of tungsten

open access: yesNuclear Materials and Energy, 2016
AbstractThe irradiation hardening and microstructures of pure W and W–3%Re for up to 5.0 dpa by self-ion irradiation were investigated in this work. The ion irradiation was conducted using 18 MeV W6+ at 500 and 800°C. A focused ion beam followed by electro-polishing was used to make thin foil specimens for transmission electron microscope observations.

Elastic Strain Associated with Irradiation-Induced Defects in Self-Ion Irradiated Tungsten

open access: yesSSRN Electronic Journal, 2022
Elastic interactions play an important role in controlling irradiation damage evolution, but remain largely unexplored experimentally. Using transmission electron microscopy (TEM) and high-resolution on-axis transmission Kikuchi diffraction (HR-TKD), we correlate the evolution of irradiation-induced damage structures and the associated lattice strains ...

In-situ annealing of self-ion irradiation damage in tungsten [PDF]

open access: yesMRS Proceedings, 2014
ABSTRACTIn our earlier work [1] microstructural evolution in tungsten under self-ion irradiation was investigated as a function of temperature and dose by in-situ 150 keV W+ ion irradiations on the IVEM-Tandem facility at Argonne National Laboratory (ANL). The present work focuses on the thermal stability of this damage.

In situ observation of deuterium trapping in self-ion irradiated tungsten [PDF]

open access: yesJournal of Nuclear Materials, 2013
Abstract Characteristics of irradiation-induced hydrogen trapping in tungsten were investigated by observing deuterium concentration profiles under continuous deuterium plasma exposure. Tungsten samples called A3 and A4 were 1.5-MeV W irradiated with an average of 0.63 and 4.2 dpa, respectively, and another sample called A5 was 5.0-MeV W irradiated ...

Nanoindentation of model Fe–Cr alloys with self-ion irradiation

open access: yesJournal of Nuclear Materials, 2013
Abstract Pure Fe and Fe–Cr alloys containing 3%Cr, 5%Cr, 7%Cr, 9%Cr and 12%Cr were subjected to Fe + implantation to a low dose (2.06 dpa) and high dose (6.18 dpa) with energies of 2 MeV and 0.5 MeV and at a temperature of 320 °C. This created a damage layer of approximately 800 nm depth at the sample surface. Nanoindentation tests were performed in

Magnetic effects induced by self-ion irradiation of Fe films [PDF]

open access: yesPhysical Review B, 2016
Iron magnetic moment enhancement is observed following the irradiation of iron films with 490 keV Fe$^+$ at room temperature. The iron magnetic moment enhancement increases to saturation with irradiation dose. Theenhanced magnetic moment decays exponentially to its value before the irradiation with a time constant of 5.2 months.

Preferential Amorphization at Extended Defects of Self-Ion-Irradiated Silicon

open access: yesPhysical Review Letters, 1999
Nucleation of an amorphous Si layer is shown to occur preferentially at a thin band of dislocations during self-ion-irradiation of silicon at elevated temperatures. This process occurs even when the defect band is well separated from the peak of the ion damage distribution.

Elastomer treatment by arc metal deposition assisted with self-ion irradiation [PDF]

open access: yesSurface and Coatings Technology, 1999
The problems of the friction of elastomer articles in contact with other parts, involved in a rotating or reciprocating motion, mould release and mould fouling in rubber industry have prompted research into the deposition of metal layers on rubber.
