Abstract
This paper presents a study by Transmission Electron Miscroscopy of the deformation microstructure in the γ phase of a TiAl alloy crept at 850 °C under 150 MPa. A never observed population of dislocations is evidenced and characterized. It is shown that their Burgers vector is of [001] type and that they are moving by pure climb in the (001) planes. The reasons of the presence of these dislocations are discussed
