In the past few decades, titanium metal matrix composites have increased demand due to their vast application in the aerospace, biomedical and automotive industries. The spark plasma sintering process is one of the advanced techniques studied by various researchers during the fabrication of the TMCs. In the current work, the influence of sintering temperature and wt.% of multi-layer graphene (MLG) on hardness and elastic modulus of TMCs were studied. A parametric study of the SPS process was carried out by designing experiments using the response surface methodology. Analysis of variance was performed to investigate the influence of input factors and their interactions on the output responses. It was observed that both wt.% of MLG and sintering temperature had a substantial impact on the mechanical characteristics of the fabricated TMCs. Results show that sintering temperature contributed 42.15% and wt.% of MLG contribution was 55.40% in determining the hardness of the nanocomposites, while % contribution of sintering temperature and wt.% of MLG were 49.24% and 48.61%, respectively, in determining elastic modulus.
