Abstract
The coalesced γ″ precipitate in the aged nickel-base superalloy has been investigated using a high resolution electron microscopy. The encounter of γ″ precipitates during aging formed the coalesced precipitate that consists of several domains which keep the original orientation before encountering. The thickness of boundary in the coalesced γ″ precipitate was in the range of zero to a few atom layers.
