N2 - Homogenous thin foils of titanium with oxygen in interstitial solid solution covering the broad solubility range of O in h.c.p. Ti, were used to investigate the sink-in and pile-up occurring during nanoindentation. The anisotropic response and indent areas were accurately analyzed with atomic force microscopy. The mechanical properties and the indent areas were assessed using both the Oliver&Pharr method and a newer method incorporating corrections for indenter geometry and an improved parameter extraction. The newer method accurately accounts for pile-up.
