Resumo
The onset of plasticity during nanodeformation of a bulk TiN specimen is studied by the nanoindentation. It is shown that with a high density of dislocations in the specimen surface layer (mechanical polishing) plasticity in TiN initiates smoothly under an average contact pressure of 18.1 GPa. Hence, with a spherical approximation of the Berkovich tip, the yield strength of TiN at the nanoscale is determined to be 14.5 GPa.
