Nanoindentation-induced elastic-plastic transition and size effect in a-Al2O3(0001)

The mechanical properties of a-Al2O3(0001) have been investigated by using the technique of nanoindentation with a Berkovich indenter. Coupled with the Hertzian contact theory, a theoretical shear strength of 28 +- 2 GPa was determined from the onset of pop-in events on load-displacement curves duri...
