| Popis: | Martensitic transformation during coalescence of two Fe–20 at.% Ni nanoparticles of size d ∼3–7 nm has been studied using molecular dynamics. Orientation relationship analysis showed that Kurdyumov–Sachs orientation relationship was observed between the initial γ -phase and the final α phase (at T = 0 K ) for all of the studied cases of misorientation. A significant change in the type of contact boundaries between the two nanoparticles was obtained after the completion of the martensitic transformation, which was caused by a change in the indices of the misorientation axis of the particles and in the number of symmetry elements for it. |
