Abstract
This paper presents the results of study on indentation size effects in structural metals/alloys (6061 aluminum alloy, titanium and Ti–6Al–4V) at the micron scale. The size dependence of indentation hardness is explained using strain gradient plasticity theories introduced by Nix and Gao (J. Mech. Phys. Solids., 46 (1998), 411–425). Resulting material length scales are also compared with the underlying microstructures and previously reported values in the literature. The impacts of strain hardening models from stress-strain curves on the predicted length scales are explored. Implications of the results are discussed for the modeling of plasticity and hardness at the micron-scale.
