Abstract Scope |
The influence of variations in the TiC content employed during spark plasma sintering (SPS) of nickel-titanium carbide composites on its microstructure and mechanical properties has been investigated systematically. Mechanical alloying has gained special attention as a powerful non-equilibrium process for fabricating amorphous and nanocrystalline materials, whereas spark plasma sintering (SPS) is a unique technique for processing dense and near net shape bulk alloys with homogenous microstructure. Mechanical alloying was performed using planetary high energy ball mill with 400 rpm and ball to powder ratio 15:1 for 24 hours. Bulk Ni-TiC composites (with TiC content varying from 5 to 50 wt%) were fabricated via mechanical alloying followed by SPS at 65 MPa pressure and 900-12000C temperature. There is an increase in microhardness, as well as TiC peak intensity, which has been observed with increasing TiC content. These Ni-TiC composites exhibit excellent microhardness and tribological properties as compared to pure nickel. |
