Paper Abstract

Semiempirical potentials for DO19 type Ti3Al are derived with use of the modified embedded atom method formalism. The potential function is determined by using the measured lattice constants sublimation energies, elastic constants and vacancy formation energy. The potentials are used to calculate the antiphase boundary energies and (gamma) - surfaces in a basal, prism and pyramid planes.
