Abstract

The innovative headway in nano-indentation improvement in the world of nanotechnology has empowered investigations on materials properties under unstable and dynamic conditions to offer direct evaluation of some outputs like modulus of flexibility, nanoindentation hardness and the contact stiffness among different properties. The present study explored the mechanical properties of sintered Ti (Cx, N1-x); (x= 0.9), for each composition of both carbon and nitrogen in the ceramic matrix composite used. The graphite reinforcements (0, 0.5 and 1.0 wt. % was examined by ultra-nano indentation (UNHT) strategy. Result show that higher weight percent of graphite in each of the Ti (Cx, N1-x) sintered composites had an effect on the grain morphology which resulted in undissolved graphite in the matrix. Furthermore, the moduli of elasticity and nanoindentation hardness depend on the graphite reinforcement in the matrix. The composite with 1.0 wt.% graphite exhibited hardness of 25207 MPa and elastic modulus of 400.41 GPa in Ti (Cx, N1-x) compared to pure TiC0.9N0.1, TiC0.9N0.1 +0.5wt.%Gr to other cermets with hardness of 18,835 MPa, 19209 MPa and modulus of 372.57 GPa, 393.38 GPa respectively.
