In this study, the habit planes of dislocations moving by glide and climb at 850–900° C have
been determined in three dimensions (3D) by electron tomography, using the TiAl …

We address the question of the observed pinning of 12〈 11¯ 0] ordinary screw dislocations
in γ-TiAl, which leads to the characteristic trailing of dipoles in the microstructure. While it …

Computer simulation of the core structure and glide of ordinary 1/2< 110] dislocations and<
101] superdislocations in L10 TiAl has been performed using the recently constructed …

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 …

Abstract The b= ½⟨ 110] unit dislocations in deformed TiAl alloys exhibit a unique
morphology, consisting of numerous pinning points along the dislocation line aligned …

Dislocation velocities at high temperatures in metallic systems are believed in literature to be
different for glide and climb, the values being bigger in case of glide. However, this has not …

Herein careful analysis of in situ neutron diffraction patterns obtained, while cyclically
loading highly textured polycrystalline Ti 2 AlC, a MAX phase, samples, provides compelling …

Ti3Al single crystals have been strained along the c axis in situ in a transmission electron
microscope, in order to investigate the mechanisms of glide in pyramidal planes. Between …

Pinning points anchoring Shockley dislocations and ordinary dislocations in the γ phase of
two TiAl alloys (a single-phase alloy and a lamellar two-phase alloy) are studied by in situ …

TiAl polycrystalline specimens, having the L10 structure, have been deformed at room
temperature and examined by transmission electron microscopy. The observations revealed …
