Аннотация
The influence of segregations on the processes of grain boundaries (GB)sliding and the energy characteristics of grain boundary shifts for asymmetric GBs of tilt Σ5{010}/{340}<001> and Σ5{110}/{710}<001>
in bicrystals of Al–Mg and Al–Ni alloys was studied using atomistic modeling methods. The energy of generalized grain boundary stacking faults was determined, and preferred directions and the energy barrier for grain boundary sliding were established. It is shown that Ni segregation-induced nano-faceting significantly modifies the grain boundary structure, increasing the slip resistance.
