Abstract
The localized deformation behavior of commercially pure titanium was evaluated using the micro-indentation technique. The indentations were made by a Vickers indenter in the load range of 100 mN to 3000 mN with zero holding time at the peak indentation load. The loading and unloading times were 30 s with constant loading and unloading rates. The indentation hardness decreased with the indentation load, showing the normal indentation size effect. The plastic energy dissipated during an indentation loading-unloading cycle was proportional to the 3/2 power of the indentation load and 3/4 power of the average dislocation density underneath the indentation. The effect of the indentation loading rate was examined on the time-dependent plastic deformation of the titanium at ambient temperature.
