“…In addition, the mechanisms of these different fabrication routes, described in Table 1, were explored. Carreño-Gallardo et al 52 pointed out the best hardness and strength were achieved at 2.5 wt.%. Thus, in the fabrication process, 2 wt.% of nanosized β-SiC with 95% purity and average size of 60 nm, purchased from Alfa Aesar (Germany), were mixed with aluminum fine powder of 98% purity and average particle size of 30 µm, purchased from Loba Chemie (India).…”

This paper explores new routes for flake powder metallurgy, with the aim of designing an effective route for fabricating metal matrix nanocomposites, combining high strength and good ductility. A new route that uses three speeds, instead of the two speeds characterizing the shift-speed ball milling (SSBM) route, has been suggested and implemented. the mechanisms of these routes were illustrated based on the intensity of ball-powder-ball collisions and the morphology evolution. the ball milled powder were characterized using filed emission scanning electron microscope (FESEM), X-ray diffractometer (XRD) and Energy dispersive spectroscopy (EDS) to investigate the morphology evolution of the composites powder and the homogenous distribution of the Sic nanoparticles within the Al matrix. the reinforcing adequacy and interfacial bonding of 2 wt.% SiC nanoparticles in an inductively sintered composite has been investigated. Mechanical testing of the produced bulk composites resulted in achieving superior mechanical properties, characterized by 92% higher hardness, 180% higher yield strength, 101% higher ultimate strength, and 0% loss in uniform elongation, compared with those of regular SSBM. This is attributed to the homogeneous dispersion of the reinforcement into the Al matrix.

“…At present, silicon carbide nanoparticles (SiC NP ) have been implemented as a new reinforcements because of their good thermal and electrical conductivities, chemical stability, high mechanical strength, and low friction [3e8] , improving the tensile properties of many materials (i.e., aluminum-based alloys) at different temperatures when homogenously dispersed in metal-matrix [9e12] . Some related studies also show the unique ability of SiC NP to strengthen a metal matrix, while simultaneously maintaining good ductility [9,13] .…”

“…Both load bearing and microstructural strengthening effects coexist and are related to the distribution, volume fraction and size of the reinforcement 22 , 25 . The strength increases with increasing the reinforcement volume fraction as well as by reducing the size of the reinforcing phase 5 , 19 , 26 – 32 , provided that the reinforcing particles are homogeneously dispersed in the matrix and no significant reinforcement clustering occurs. Particular important for large volume fractions of reinforcement and/or small particle size is the reduction of the matrix ligament size (λ), which can be regarded as the average distance between adjacent reinforcing particles, and results in a similar strengthening as the Hall-Petch effect observed for grain refinement 22 .…”

Strengthening of alloys can be efficiently attained by the creation of harmonic structures: bimodal microstructures generated by controlled milling of the particulate precursors, which consist of coarse-grained cores embedded in a continuous fine-grained matrix. Here, we extend the concept of harmonic structures to metal matrix composites and analyze the effectiveness of such bimodal microstructures for strengthening composites consisting of a pure Al matrix reinforced with Fe3Al particles. Preferential microstructural refinement limited to the surface of the particles, where the Fe3Al phase is progressively fragmented, occurs during ball milling of the Al-Fe3Al composite powder mixtures. The refined surface becomes the continuous fine-grained matrix that encloses macro-regions with coarser reinforcing particles in the harmonic composites synthesized during subsequent powder consolidation. The generation of the bimodal microstructure has a significant influence on the strength of the harmonic composites, which exceeds that of the conventional material by a factor of 2 while retaining considerable plastic deformation. Finally, modeling of the mechanical properties indicates that the strength of the harmonic composites can be accurately described by taking into account both the volume fraction of reinforcement and the characteristic microstructural features describing the harmonic structure.
