4. Conclusion
To summarize, this study examined the effect of crystallographic
orientation on mechanical properties of individual grains,
in a polycrystalline commercially pure titanium. We used the EBSD
technique to provide a mapping of crystallographic orientations of
different polycrystalline areas of a sample and then the nanoindentation
technique to probe the mechanical properties of each
grain spotted on the orientation maps. For a better understanding,
and a highlighted visual effect, the results have been presented as
“inverse pole figures in hardness” (HIPF) and “inverse pole figures
in elastic modulus” (EIPF). It has been proved that the hardness
varies significantly with orientation. On the contrary, the evolution
of the elastic modulus appears less sensitive to grain orientation.
The nanoindentation measurements carried out in the present
work show that hardnesses of grains presenting a basal plane
possess higher values than grains presenting a prismatic plane of
about 100 HV with the Berkovich tip and about 140 HV with the
spherical tip.
