摘要
The dissociation of dislocations into partials bounding an extrinsic stacking fault is studied in an atomistic simulation of aluminium. An embedded-atom-type potential is employed. Of two possible extended configurations, 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 dislocations in the arrays.
