Abstract
The nanocontact plastic behaviour of single-crystalline Ta (1¿0¿0), Ta (1¿1¿0) and Ta (1¿1¿1) was studied as a function of temperature and indentation rate. Tantalum, a representative body centred cubic (BCC) metal, reveals a unique deformation behaviour dominated by twinning and the generation of stacking faults. Experiments performed at room temperature exhibit a single pop-in event, while at 200¿°C, above the critical temperature, a transition to multiple pop-ins was observed. The exp...
