The nanoindentation test has been recently developing to evaluate local mechanical properties in micro areas of various materials. In the present study, the nanoindentation tests were performed to grains in polycrystalline pure titanium, which is hexagonal close-packed crystal structure thus has less slip systems than the other crystalline structures. Then the relationship between the crystal orientation and the resultant indentation shape was investigated. The experimental results show the clear orientation dependence of the indentation shape. The obtained hardness value tends to increase when <0001> direction approaches to the direction normal to the sample surface.
