Methods of x-ray diffractometry are used to investigate the influence of plastic deformation on the state of the longrange order in alloys with the L1 2 , L1 2 (М), and L1 2 (MM) superstructure. It is demonstrated that the heterogeneous order-disorder phase transition accompanied by intensive accumulation of antiphase boundaries occurs under plastic deformation. The antiphase boundaries play an important role in the destruction of long-range order. Based on the available experimental results, a model of destruction of long-range order is constructed that takes into account the dislocation mechanisms of accumulation of antiphase boundaries under deformation.

Results of mathematical modeling of plastic strain superlocalization are presented with allowance for dislocation redistribution into dislocation walls. The model based on the concept of hardening and rest is used to construct equations describing kinetics of dislocations and substructure transformations. It is demonstrated that depending on the scenario of the strain model evolution in the microvolume of a deformable body, different types of localization are possible under the influence of stress concentrators.

Dislocation Creep of Single-Crystalline L12-Superlattice Intermetallic Compounds

The creep phenomenon observed in ordered alloys and intermetallics with the L1 2 -superlattice structure are considered. A mathematical model that accounts for the superlattice dislocation locking mechanisms at work during creep of the single crystals is constructed. Superposition of the thermal activation mechanisms of the superlattice dislocation motion and locking is shown to give rise to an anomalous temperature dependence of the creep rate. .
