Learning on ScreenDislocation Movements in Aluminium-1%-Magnesium Alloy
- Synopsis
- For this production specimens of up to 8% pre-deformation of an aluminium-1%-magnesium alloy have been investigated in a transmission electron microscope using an acceleration voltage of 100 kV. The activation of the dislocation movement was achieved with the aid of a heating device built into the microscope or by the beam itself. In the latter case dislocation movement is probably due to stresses induced in the specimen by surface contamination. The following phenomena may be observed: the formation of dislocations at dislocation sources; the onset of movement of individual dislocations; single and multiple slip; cross slip; the interaction of dislocations and the disintegration of a dislocation loop.
