Abstract

In this paper, mechanical behavior of TiAlV/TiAlVN bilayers was studied by means of nanoindentation experiment simulated using ANSYS software. In the simulations, a Vickers type diamond tip, a steel substrate and TiAlV/TiAlVN bilayers distributed in a constant thickness of 2 μm by an axisymmetric geometry were considered. The parameters used in the simulation as Young’s modulus E, Poisson ratio ν and yield stress σe for TiAlV and TiAlVN were 113.6 GPa and 350 GPa, 0.342 and 0.2, and 830 MPa and 870 MPa respectively. Results showed the radial stress distribution seems to be tooth -like and the maximum shear stress decreased as the number of bilayers increased
