Point defect formation in γ-TiAl deformed in single slip was investigated by molecular dynamics simulations. Dislocations gliding on nearby planes react to form vacancies, interstitials and clusters of these, including planar arrays of crowdions and dissociated prismatic loops. The motion of these defects and their interaction with mobile dislocations were analysed. These point defects could interact with others or with dislocations forming jogs hindering dislocation motion.
