Figure 1.
Dynamic ultra-micro-hardness testing system used in this study. (a) Schematic image of the geometry of the Berkovich indenter tip. Tip height (L) is defined as L = (1/3) (L1 + L2 + L3). The photograph is the indented surface of the sample after testing. (b) Schematic illustration of the micro-indentation load versus penetration depth curve obtained from the testing.
