Embedded-atom interatomic potentials and simulation of planar defects in intermetallic Ti3Al

superpartial dislocation in the prism plane of the D019 superlattice is studied by computer simulation. Atomic interaction potentials for Ti3Al are derived with the embedded atom method. The core of the superpartial dislocation is found to have three different configurations (of I′, I, and II types) in nonequivalent prism planes

AbstractThe energies of surface defects in the basal and prismatic planes, as well as in the planes of type I and type II pyramids, are calculated by using N-particle interaction potentials for the Ti3Al intermetallic with the D019 superlattice.
