Dislocation climb in an Al-Pd-Mn quasicrystal deformed at low temperature

摘要

Dislocations and phason faults have been imaged in a transmission electron microscope in an icosahedral Al-Pd-Mn quasicrystal deformed at 300℃. The contrast of these dislocations has been studied. The analysis of Burgers vectors indicates that their motion takes place by climb.
