Influence of tip bluntness on the depth-dependent nanoindentation hardness

Published

Author(s)

C S. Kim

Abstract

Nanoindenter tip bluntness modifies the depth-dependent hardness relationship given by the Nix-Gao model. At shallow depths, fewer geometrically necessary dislocations are needed to accommodate the blunted tip. The experimentally measured ratio of plastic to total contact depth decreases and the hardness decreases, relative to the idealized Nix-Gao model.
