The interstitials on GB plane energetically prefer to accumulate into a cluster.
- •
Interstitial clusters tend to present in a linear structure along direction [hmlsrc">he MathML source" class="mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0375960115010026&_mathId=si2.gif&_user=111111111&_pii=S0375960115010026&_rdoc=1&_issn=03759601&md5=7b7b9fb9d6ad2d88abe6b3a1356c3b34">

Interstitial clusters will be more stable with the increase of their lengths.
- •
The ability of interstitials healing vacancies is reduced when clusters formed.
- •
Interstitials in clusters still can be efficiently emitted to annihilate vacancies.
