The following video clips were made as a single crystal of cadmium underwent deformation in a scanning electron microscope (SEM) chamber.
Warning: you will need a high speed Internet connection to view these videos without a long wait! It takes approximately 6 mins per MB to receive data via a 56K modem. The video clips open in a new window, and can be left to download in the background while you continue using this window.
The videos of the demonstration are in QuickTime format and require your browser to have the QuickTime 5 (or higher) plugin installed. If necessary download the plugin from the QuickTime download site.

The trace of the slip planes can be seen. Markers have been dropped onto the surface of the crystal to allow the relative movement of parts of the crystal to be clearly seen. - Slip proceeding

An unusually large slip step can be seen on the left-hand edge of the specimen. As slip proceeds, the slip planes rotate towards the tensile axis, but the large slip step does not increase in size. - A cadmium crystal

The mode of fracture is ductile tearing. Note how the angle of the fracture surfaces mimics the angle of the slip planes in the deformed crystal.
