Аннотация
The paper presents a mathematical model of thermal and strain hardening of alloys having L12 superstructure which allows calculating the atomic long-range order (LRO) parameter depending on the deformation degree under various temperature and loading conditions. The observed non-monotonic change in the atomic LRO parameter during plastic deformation occurs due to the two types of competitive processes. These processes are caused by the motion and accumulation of the deformation defects and their healing due to the migration of point defects of different nature. The competitiveness between these two types of processes leads to the periodical destruction and reconstruction of the atomic LRO parameter, while the equilibrium between them can stabilize it after which it continues to be stable despite the deformation.
