Abstract
The dissociation of dislocations into partials bounding an extrinsic s tacking fault is studied in an atomistic simulation of aluminium. An e mbedded-atom-type potential is employed. Of two possible extended conf igurations, one retains an extrinsic stacking fault in a stable array while the other converts to an array with an intrinsic stacking fault. The results are related to interaction forces among the partial dislo cations in the arrays.
