Abstract Molecular dynamics simulations are carried out to study the incipient dislocation plasticity in Ni3Al. Dislocation nucleation is found to occur preferentially at energetic atomic clusters with larger-than-average relative displacements. From the simulated distribution of the atomic relative displacements, a scaling model is proposed to predict the size dependence of the incipient plasticity condition in real-sized specimens
