Kubiak * Department of Chemistry and Biochemistry, University of California, San Diego, Gilman Drive, La Jolla, California With increasing neutron fluxes and addition of He atoms, the bubbles may keep growing, leading to void swelling, hardening, and embrittlement [4,43,44,45]. Therefore, to better simulate the neutron radiation damage with heavy ion irradiation technique, it has been suggested that pre-injection or simultaneous implantation of He may be necessary Author: Cuncai Fan, Zhongxia Shang, Tongjun Niu, Jin Li, Haiyan Wang, Xinghang Zhang. defects under various conditions of temperature, or under vacuum using vapor pressure change as the agent: x pressure or x . vacuum Another special case is the use oflight.

influence of injected interstitials on void swelling in 316 steel under ion bombardment by S. M. Murphy Download PDF EPUB FB2

The forward shift in depth between peak swelling and peak dose is proposed to be a consequence of suppression of void nucleation by injected interstitials.

The swelling behavior in the front portion of the ion range mirrors that of neutron-induced swelling in this steel, exhibiting significant curvature with increasing dose as the swelling rate approaches the terminal swelling rate of 1%/tecknoquestllc.com by: 6.

In this study MeV self-ion irradiation of pure iron was used to study the influence on void swelling of the depth-dependent defect imbalance between vacancies and interstitials that arises from various surface effects, forward scattering of displaced atoms, and especially the injected interstitial tecknoquestllc.com: Sun, C.

Influence of injected interstitials on the void swelling in two structural variants of L stainless steel induced by self-ion irradiation at °C.

The difference lies merely in the magni- tude of the suppression; it is much more dramatic for void nucleation than for void growth. If void swelling after ion bombardment is measured either from step heights or by microscopic examinations in the peak damage region the effect of the injected interstitials Cited by: The larger step height to peak void volume ratio in material neutron irradiated at 58^ results from the lower sink strength in this material at all ion bombardment temperatures.

The theory shows that injected interstitials are important in suppressing void growth Cited by: In comparison, void swelling at peak dpa for peaks beyond nm, with ∼90% swelling in the – nm region where injected interstitials normally suppress void nucleation, a finding which cannot be explained by citing only the defect imbalance effect mentioned in previous studies [24,27,48].Cited by: 1.

In one year of irradiation, the void swelling would be %. Void lattices. At this point, it is worthwhile to summarize the sequence of events that voids pass through.

The first stage is nucleation, during which small voids are produced by agglomeration of vacancies in the bulk. In one of our previous void swelling simulation studies, conducted on pure iron at °C using MeV Fe 2+ ions, we have shown that there is a ~ nm denuded zone at the ion-incident surface, but most importantly, the void distribution does not extend very far into the region containing the injected tecknoquestllc.com: Tianyao Wang, Hyosim Kim, Frank A.
