摘要：

L1(2) precipitate shearing processes by (a/3)<112> dislocations during in situ straining of a superalloy in a transmission electron microscope are reported. Information about the core structure of such dislocations is obtained from the way they split when they get out of a precipitate. We conclude that a further dissociation into two identical Shockley partials occurs.
