Abstract
L12 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.This publication has 7 references indexed in Scilit:
