Abstract

Here we report for the very first time, the detailed mechanisms of the formation of `micro pop-in' events observed during nanoindentation at 10-1000 mN load in a 10 ZTA (i.e., 10 vol% zirconia toughened alumina) ceramic. Explicit analysis of the experimental results backed up by comprehensive Field Emission Scanning Electron Microscopy (FESEM) based evidences suggests that the maximum shear stress (tau(max)) generated underneath the nanoindenter, the formations of shear bands and localized microcrackings play significant role in the initiation of nanoscale plastic events in the present ZTA ceramic.
