Molecular dynamics study of α↔γ transformations in Fe-Ni nanoparticles
Size effect in Fe - Ni alloy nanoclusters has been studied by the molecular-dynamics method using N -body interatomic interaction potentials. It has been found that in Fe-Ni clusters with sizes d<1.5 nm, the α→γ transformation does not occur. During heating the initial bcc configuration turns into an icosahedral through polytetrahedral or amorphous- like configuration.
