Abstract
The coalesced gamma'' precipitate in the aged nickel-base superalloy h as been investigated using a high resolution electron microscopy. The encounter of gamma'' precipitates during aging formed the coalesced pr ecipitate that consists of several domains which keep the original ori entation before encountering. The thickness of boundary in the coalesc ed gamma'' precipitate was in the range of zero to a few atom layers.
