Abstract
The destruction of long-range atomic order due to the accumulation of antip hase boundaries that are generated by superdislocations and single dislocat ions during plastic deformation of L1(2)-type ordered alloys is considered. A mathematical model of strengthening and the destruction of long-range or der caused by the deformation-induced multiplication of shear-forming dislo cations is formulated with allowance for the change in the type of shear-fo rming dislocations from superdislocations to single dislocations.
