In this work the influence of the geometry of the Vickers indenter tip on relevant indentation properties is investigated during instrumented indentation operated in the macro range (i.e. with forces ranging from 2 to 200 N) and carried out in the case of a homogenized (i.e. heat treated) TiAl alloy.

The instrumented macro-indentation test is simulated by Comsol Multiphysics using a full 3D structural mechanics contact model involving large displacements, strong singularity and non linearity. Special attention is given to bluntness effects of the Vickers indenter.
