“…Since the silicon content in the AC8A alloy used as the matrix in the present study was 12 mass%, it can be said that the results obtained from Fig. 4 support the previous reports 11,12) , which have already been mentioned in the introduction. In contrast, the Al 4 C 3 was not observed in the pitch-based ber composites and the interfaces were smooth even though the pure aluminum was used as the matrix (Fig.…”

“…4(c) and (d). As stated in the introduction, it was reported that the pitch-based carbon ber is more stable than the PAN-based carbon ber in the aluminum melt [8][9][10][11][12] , and the results obtained from The aging curves of the unreinforced AC8A alloy and its composites are shown in Fig. 5.…”

“…Thus, bers with a high degree of graphitization (containing highly-oriented basal planes with few exposed edges) and a smooth surface with little topography are ideal for hindering the nucleation of carbides, due to their lack of surface defects 11) . It has also been reported that the addition of silicon to aluminum suppresses the interfacial reaction between the carbon (graphite) and matrix 11,12) . This reaction could occur not only during the melt in ltration, but also during the subsequent heat treatment (when the matrix is the heat treatment strengthened type) and/or in use under a high temperature environment.…”

“…Casting techniques, such as the melt in ltration process, have been widely used for fabricating the carbon ber-reinforced aluminum composites [5][6][7][8][9] . Some researchers [8][9][10][11][12] reported that the PAN-based carbon ber easily reacted with the aluminum melt and produced a mechanically and chemically unstable Al 4 C 3 at the ber-matrix interface during the casting process. According to these reports, the pitch-based carbon ber was more stable than the PAN-based carbon ber in the aluminum melt.…”

Pure aluminum and AC8A aluminum alloy matrix composites, which were reinforced with PAN-and pitch-based short carbon bers, were fabricated by squeeze casting, then the composites were exposed to a heat treatment. The effects of the ber types, composition of the matrix, and heat treatment on the mechanical properties of the composites were investigated. The bers were in a random planar arrangement in the composites. Although the aluminum carbide was formed due to the reaction between the PAN-based ber and pure aluminum during the casting process, there was no reaction products near the PAN-AC8A, pitch-pure aluminum and pitch-AC8A interfaces. Although the ultimate compressive strength of the PAN-based ber composite was greater than that of the pitch-based ber composite under every condition, the strength of the PAN-based ber composite degraded due to the heat treatment when pure aluminum was used as the matrix. Examination of fracture surface indicated that the lower reinforcing effect of the pitch-based ber would be due to delamination at the boundary between the highly-developed graphite crystallites in the ber. A hardness measurement of the bers in the composites using a nano-indenter revealed that the interfacial bonding strength between the pure aluminum and PAN-based ber degraded due to the heat treatment.

“…Copper matrix composites are suitable for a variety of applications, such as heat sinks, connectors, high performance switches, electronic packaging, resistance welding electrodes, etc., due to the combination of both very good electrical/thermal conductivity and corrosion resistance [2,3]. The most-widely-applied methods for producting copper matrix composites are based on the following: powder metallurgy methods, internal oxidation method, self-propagating high temperature synthesis process (SHS), accumulative roll bonding, mechanochemical route, and friction stir welding [4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Copper matrix composites reinforced with titanium nitride particles synthesized by mechanical alloying and spark plasma sintering Kompozyty na osnowie miedzi umacniane cząstkami azotku tytanu wytworzone w procesie mechanicznej syntezy i iskrowego spiekania plazmowego (SPS) AbstractCopper matrix composites containing ceramic particles such as carbides, borides, or nitrides have attracted much attention over the last few years. The increased interest in such materials has mainly been created by their high electrical and thermal conductivity, good mechanical and tribological properties, and microstructural stability. Among other nitrides, the titanium nitride seems to be considered as an attractive reinforcement due to its high hardness, excellent electrical conductivity, and stability at high temperatures. Moreover, its good corrosion resistance proves the uniqueness of the TiN particles above any other nitrides. In this work, Cu-10 wt.% TiN composite powders were produced by mechanical alloying and sintered by the spark plasma sintering (SPS) technique under different temperatures. The morphology and powder particle size after mechanical synthesis were inspected by a scanning electron microscopy (SEM) for all of the powder samples; chemical composition analyses (EDS) were also performed. The hydrostatic method was used to measure the density of the composite samples to analyze the influence of milling time on the process of consolidation in the composite powders. Keywords: copper matrix composites, mechanical alloying, spark plasma sintering, titanium nitrides, powder metallurgy StreszczenieKompozyty na osnowie miedzi zbrojone cząstkami ceramicznymi, m.in. węglikami, borkami i azotkami, w ostatnich latach wzbudziły spore zainteresowanie z uwagi na wysoką przewodność

Short graphite fiber/Al composites are fabricated by spark plasma sintering technique. A titanium coating synthesized on the graphite fiber surface through vacuum microdeposition is proposed to improve the interfacial bonding between graphite fibers and aluminum matrix. The influences of surface modification, sintering temperature, and graphite fiber volume fraction on relative density and thermal conductivity (TC) of the composites are systematically investigated. The results indicate that compared to uncoated graphite fiber/Al composites, the densification, interfacial bonding, and TC of titanium-coated composites are greatly enhanced. The in-plane TC of 50 vol% titanium-coated graphite fiber/Al composites sintered at 610°C is 238 W m À1 K À1 , nearly twice as high as that of uncoated composites. From the calculation based on the experimental TC by Maxwell-Garnett effective medium approach, the interfacial thermal resistance is evidently decreased by above 1 order of magnitude with the introduction of titanium nanolayer.
