Abstract
The onset of plasticity in Cr was investigated by nanoindentation using indenters with tip radii ranging from 60 to 759Â nm. The stress for incipient plasticity was found to increase with decreasing tip radius. The cumulative pop-in probability on load could be described successfully by a combined model over the full range of tip radius, indicating that the incipient plasticity might be triggered either by the homogeneous nucleation of dislocation or by the activation of existing dislocations underneath the indenter.
