Abstract

Pure nickel and three nickel containing single-phase concentrated solid solution alloys (SP-CSAs) have been irradiated using 3 MeV Ni²⁺ ions at 500 C to fluences of 1.5 x 10¹⁶ and 5.0 x 10¹⁶ cm². We characterized the radiation-induced voids using cross sectional transmission electron microscopy that distributions of voids and dislocation loops were presented as a function of depth. We also observed a various degree of void suppression on the tested samples and a defect clusters migration mechanism was proposed for NiCo. Furthermore, in order to sufficiently understand the defect dynamics in these SP-CSAs, the injected interstitial effect has been taken into account along with the 1-dimentional (1-D) and 3-dimentional (3-D) interstitial movement mechanisms.

Suppression of void formation in nickel by a dynamic trapping mechanism

Conference Sorensen, Jr, S M ; Chen, C W

The effect of carbon on void formation in high purity nickel under neutron irradiation to four fluences ranging from 4 x 10$sup 18$ to 2 x 10$sup 20$ n/cm$sup 2$ (E greater than 0.1 MeV) at 500$sup 0$C was investigated using transmission electron microscopy. In samples containing up to 84 wt ppM C, cubic voids were observed, and the void size tended to increase with increasing C content, while the void density decreased at much greater rates. Consequently, the associated swelling was seen to be steadily reduced. In samples containing 600 ppM C, void formation was completely suppressed, and anmore »« less

From suppressed void growth to significant void swelling in NiCoFeCr complex concentrated solid-solution alloy

Journal Article Fan, Zhe ; Yang, Tai-ni ; Kombaiah, Boopathy ; ... - Materialia

Void swelling can result in dimensional instability and undermine the safe operation of nuclear reactors. Current strategies to inhibit void swelling mainly focus on enhancing defect absorption and recombination by introducing high-density defect sinks. Complex concentrated solid-solution alloys (CSAs), including high-entropy alloys, can withstand severe radiation damage due to their inherent chemical complexity without interfaces. However, the underlying mechanisms for void suppression in CSAs are far from clear. In this research, we studied the void evolution with respect to irradiation depths, doses, and temperatures in equiatomic NiCoFeCr under 3 MeV Ni ion irradiations. At relatively low doses (16 and 54more »« less

Radiation-induced segregation on defect clusters in single-phase concentrated solid-solution alloys

Journal Article Lu, Chenyang ; Yang, Taini ; Jin, Ke ; ... - Acta Materialia

A group of single-phase concentrated solid-solution alloys (SP-CSAs), including NiFe, NiCoFe, NiCoFeCr, as well as a high entropy alloy NiCoFeCrMn, was irradiated with 3 MeV Ni²⁺ ions at 773 K to a fluence of 5 10¹⁶ ions/cm² for the study of radiation response with increasing compositional complexity. Advanced transmission electron microscopy (TEM) with electron energy loss spectroscopy (EELS) was used to characterize the dislocation loop distribution and radiation-induced segregation (RIS) on defect clusters in the SP-CSAs. The results show that a higher fraction of faulted loops exists in the more compositionally complex alloys, which indicate that increasing compositional complexity canmore »« less

Effects of implanted hydrogen and helium on cavity formation in self-ion irradiated nickel

Thesis/Dissertation Bullen, D B

Interstitial gas atoms, such as hydrogen and helium, introduced into the lattice of a metal via (n,p) and (n,..cap alpha..) reactions or by permeation and diffusion, can act as nucleation sites for cavity formation. Electrostatic accelerators are used to simulate neutron displacement damage and interstitial gas atom effects in preinjection and co-implantation irradiation studies. In this investigation, specimens of high purity nickel were preinjected with hydrogen or helium at 25/sup 0/C and subsequently irradiated with nickel ions under various conditions. Irradiated samples were prepared for transmission electron microscopy analysis using a cross section technique which allowed evaluation of depth dependentmore »« less
Spatial variation in void volume during charged particle bombardment: the effects of injected interstitials

Conference Lee, E H ; Mansur, L K ; Yoo, M H

Experimental observations of the void volume at several depths along the range of 4 MeV Ni ions in 316 stainless steel are reported. The specimens were first preconditioned by neutron irradiation at temperatures of 450 and 584/sup 0/C to fluences of approximately 8 x 10/sup 26/ n/m/sup -2/. The void volume after ion bombardment to 60 dpa at the peak damage depth is significantly lower at the peak damage depth than in the region between that and the free surface. The ratio of the step height to void volume at the depth of peak energy deposition between regions masked frommore »« less
