Based on this analysis, a new method for evaluating the bluntness magnitude of a Berkovich indenter was proposed. This method was examined by the experimental results of indention loading curves for pure nickel and aluminum alloy 8009, and good agreement was obtained. For thin metal films deposited on hard substrate, a method is established for determining the yield strength and hardening index of the film from nanoindentation loading curve.
