Multi-walled carbon nanotubes (MWCNT) reinforced nickel matrix nanocomposites (Ni-CNT), and Graphene nanoplatelet (GNP) reinforced nickel matrix nanocomposites (Ni-GNP) are fabricated using two different types of ball milling techniques. Dry milling and wet milling processing routes are utilized to achieve the dispersion of MWCNT/GNP in the nickel matrix, and the nanocomposites are consolidated using Spark plasma sintering (SPS) technique. Ni-CNT/GNP powder with varying weight percentage is milled for up to 12 hours to investigate the effect on the microstructure, grain size, and dispersion of MWCNT/GNP in the nickel matrix. Ni-CNT/GNP nanocomposites exhibited enhanced improvement in the mechanical properties in comparison with pure nickel. Mechanical properties of the composites are evaluated to understand the effects of MWCNT/GNP dispersion on the strength of the composites. The applicability of the micromechanical models in predicting the strengthening effect of the reinforcement in the matrix is analyzed.
