| Abstract Scope |
The study presents the impact of incorporating multi-walled carbon nanotubes (MWCNTs) on the mechanical and tribological properties of Inconel 718 (IN718) alloys for advanced structural applications. IN718 metal matrix composites (MMCs) with varying CNT concentrations (0 wt%-1 wt%) were produced using high-energy ball milling and spark plasma sintering. XRD and SEM/EDS were employed for microstructural examination and to understand the interaction between IN718 and CNT. The study showed the uniform dispersion and grain refinement effect of CNT in the IN718 matrix. Microhardness measurements, tensile and wear testing were performed on IN718-CNT MMCs, and the sample with 0.5wt% CNT exhibited the best properties with an increase in microhardness and yield strength by ~20.2% and ~71.4%, respectively, and a reduction in the coefficient of friction and wear rate by ~29% and ~84% respectively. This research aims to promote the development of MMCs reinforced with CNT and broaden their potential applications. |
