“…Several researches have been conducted so far to improve the interaction and incorporation of B 4 C in molten Al, including preheating particles to form boron oxide, surface preparation techniques, coating with Ti, and applying Ti-containing flux [6][7][8][9][10][11]. As a result of the interfacial reaction between the reinforcement and matrix, an interface forms, which plays an important role in mechanical properties of composites [12][13][14], and hence, lots of research has been conducted on this subject [2,3,12,13].…”

Zirconium was used in Al-Mg/B 4 C composite to improve compocasting efficiency by increasing particle incorporation. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) results revealed that by addition of zirconium a reaction layer containing Zr, Al, B and C is formed on the interface of B 4 C-matrix. X-ray diffraction (XRD) analysis of extracted particles unveiled that the ZrB 2 phase is the main constituent of this layer. Formation of ZrB 2 is an exothermic reaction which can rise temperature locally around particles and agglomerates. Rising temperature around agglomerates in conjunction with turbulent flow of melt facilitates agglomerates wetting and dissolving into molten aluminum.As the result, final product contains more uniformly distributed B 4 C particles. Besides enhancing compocasting efficiency, addition of Zr and formation of reaction layer by improving particle matrix bonding quality, led to increase in ultimate tensile strength and elongation of the composite around 8% and 30%, respectively. SEM observations of the fracture surfaces confirmed that a proper bonding presents at the interface of particles and matrix in presence of Zr.

“…Copper matrix composite materials have gained significance in order to overcome this problem. Reinforcements such as carbide [9], oxide [10], nitride [11], carbon nanotubes [12], graphene [13], and diamond [14] have been added into copper in the literature. On a macro-scale, metal matrix composite materials are made up of a metal or alloy matrix and mostly particulate reinforcement material; on a micro-scale, hybrid composites are made up of more than one reinforcing element with distinct properties added to the matrix [15].…”

Bu çalışmada toz metalürjisi ile üretilen Cu-Cr-B4C-CNF hibrit kompozitlerin mikroyapı özellikleri araştırılmıştır. Mikroyapı özellikleri optik, SEM-EDS ve XRD analizleri ile incelenirken, mekanik özelliklerin tespiti için sertlik testi yapılmıştır. Mikroyapı sonuçları, özellikle EDS-MAP analizi takviye elemanlarının bakır matrisi içerisinde nispeten homojen dağıldığını göstermiştir. Karbon nanofiber nano boyuta sahip olduğu için daha büyük büyütmeli SEM fotoğraflarında tespit edilmiştir. Mikroyapıda Cu, CrB2, Cr2B3 ve C fazları tespit edilmiştir. Kompozitin sertlikleri takviye ilavesiyle artış göstermiş ve CNF’nin % 1 oranında maksimum değere (72.5 HB) ulaşmış, bu CNF oranından sonra sertlik değerinde çok az miktarda azalma meydana gelmiştir. Katkısız bakır numuneye göre Cu-8B4C-6Cr-1CNF hibrit kompozitin sertlik değerinde yaklaşık %54 artış meydana gelmiştir.

Tailoring mechanical properties of the nanowire (NW) with intricate composite structure helps to design nanodevices with novel functionalities. Here, we performed in situ tensile deformation electron microscopy for the evaluation of the mechanical properties of the focused ion beam (FIB) irradiated silicon nitride (Si3N4) nanowires (NWs). Young’s modulus of the FIB-fabricated NWs was mediated between the range of 522 and 65 GPa by modifying the shell thickness of the core–shell structure. The ion-beam-induced amorphization is found to induce the structural transition from an utter crystalline state to a composite NW with an amorphous shell, which results in a brittle-to-ductile transition and an unexpected plastic deformation. These results have practical implications for optimizing nanostructures with the desired mechanical properties, which are of fundamental relevance in designing and fabricating nanomechanical devices.
