“…This shows that the nanocomposite processed through ultrasonic dispersion and microwave sintering technique exhibits a substantial improvement in micro hardness values compared to base aluminum. It is also being found that the values are superior to the results obtained from other processing methods on the same material [51,52]. The grouping of SiC/Al 2 O 3 and graphene is capable of excellent microwave absorption capacity [53].…”

Graphene is a new class of material in carbon group with strong sp 2 -hybridized 2D-sheet like nanomaterial. In order to make an effective utilization of their astounding properties, they are currently used in the form of reinforcements in various proportions in metals and its alloys to fabricate the nanocomposites. Graphene is incorporated in oil and grease at nano range that results in higher load-carrying capacity compared with that of raw grease and oils without additives, which shows that graphene possesses self-lubricating capacity. Graphene is a planar sheet-like structure (2D), with more contact surface area in the developed composites that can make them suitable for industrial applications with well-established tribological performance. The novelty of this work focuses on the role of graphene addition in enhancing the wear performance aluminum composites to replace the conventional materials by graphene composite combinations. The current chapter explains the processing and tribological performance of graphene-aluminum composites and its effect with various hybrid combinations of MWCNT/SiC/Al 2 O 3 . Dispersion of graphene is carried out through ultrasonic liquid processor followed by ball-milling aluminum powder. Thus prepared precursors are vacuum-pressed and microwave-sintered. Graphene in the nanocomposites has resulted in significantly improving the tribological properties, where it gives the wear resistance by creating a solid, lubricant layer between the sliding surfaces.

“…And later, they attempted series of studies on heating of metals in the separated Electric (E-) and magnetic (H-) MW fields (Chen et al, 2002, Roy et al 2002. In Europe, metal heating studies also have been performed (Rodiger et al1998, Leonelli et al 2008. These reports and activities motivated the MW researchers to be further directed to the metal heating studies.…”

“…This heating mechanism is advantageous due to the following facts: (i) enhanced diffusion processes, (ii) reduced energy consumption, (iii) very rapid heating rates and considerably reduced processing times, (iv) decreased sintering temperatures, (v) improved physical and mechanical properties, (vi) simplicity, (vii) unique properties, and (viii) lower environmental hazards. These are features that have not been observed in conventional processes [5][6][7][8][9][10].…”

Abstract:Metal matrix nano-composites containing copper and ZrO 2 (8-YSZ) were sintered by microwave using mixtures of Cu and 1 wt.%, 2 wt.%, 3 wt.%, 4 wt.% and 5 wt.% of zirconia powders for 20min. The zirconia content up to 5 wt.%, resulted in an increase of 62.5% and 21.9% in micro-hardness and compressive strength respectively, and slight decrease in relative density and electrical conductivity (% IACS). In addition, field emission scanning electron micros copy (FESEM) and SEM fitted with EDX were used to characterize the sintered nano-composites.
