Abstract

This paper presents the results of an experimental study for nano-indentation size effects for different face centered cubic metals with different purities. The selected materials are: Silver, Copper, Aluminum, Lead, and Nickel. Nano-indentation tests are run using a Berkovich indenter with continuous stiffness measurement procedure where hardness is measured continuously with indentation depth. The results show three distinctive regions for the indentation size effects for the material, where hardness could increase or decrease with increasing indentation. This behavior is modeled through a proposed simple power law model, which includes the effect of grain boundaries.
