“…Aluminum alloys have excellent electrical, thermal conductivity and high ductility [9]. Thus, aluminum boron carbide composite materials have gained a greater attention due to its exhibition of combined properties of engineering ceramic and metal, which appropriately meet the requirements of modern industry including light weight, high strength, high hardness and high wear resistance [10][11][12].…”

To reveal the formation and wear mechanisms of rheo-formed aluminum alloy -B 4 C composites, A356 alloy − 10 mass% B 4 C composite material was fabricated by semi-solid stirring rheo-casting and rolling process. The presence of Al 3 BC was confirmed by XRD analysis and hinted that chemical bonding formed at interfaces between aluminum matrix and B 4 C particles. Tensile test results demonstrated that addition of B 4 C facilitated improving the tensile strength by refining matrix and providing particle strengthening. Failure tests revealed that the failure type of the composite transferred from interfacial debonding to particle cracking with increasing wear load. The wear rate of the composite was approximately 48% lower than that of aluminum alloy under 60 N load. The friction coefficient of the composite under 60 N load also significantly decreased due to formation of B 2 O 3 and H 3 BO 3 as solid lubricants. OPEN ACCESS RECEIVED

“…Bodukuri et al [13] prepared AMMC of Al-SiC-B 4 C by sintering of mechanically ball milling procedure in powder metallurgy procedures considering three different blends of configurations in volume fractions, viz., 90%Al 8%SiC 2%B 4 C, 90%Al 5%SiC 5%B 4 C and 90%Al 3%SiC 7%B 4 C. It is observed that the affinity to shrink through sintering process appears to get reduced with improvement in apparent density and the utmost improvement in tap density was identified during the initial tapping period and finally the tap density turns out to be constant. With decreasing percentage of boron carbide, hardness value too decreases.…”

Effect of turning parameters on chip generation during machining aluminum composite is studied in this work. Turning of Al-4%Cu-7.5%SiC composite material prepared through powder metallurgy procedure was chosen as the workpiece, machined using uncoated carbide insert TNMG 120404. Chips produced during machining were studied by measuring the thickness and were used along with uncut chip thickness to determine the chip thickness ratio. 99.85% pure aluminum was added with 4% volume fractions of copper and with silicon carbide particulates of 7.5%. To visualize the distribution of reinforcement phases in matrix, scanning electron microscope is used. Taguchi's methodology of design of experiments was adopted for designing a L 9 (Latin square) orthogonal array for experimental investigation, and from analysis of variance, cutting speed influencing the formation of chip by 64.13%, continuing with depth of cut by 35.26%, was identified. Confirmation test accomplished with ideal conditions produces a better chip condition.

“…In conventional Metal matrix composites (MMCs), the most generally utilized reinforcements are ceramics materials, such as B 4 C, SIC, Al 2 O 3 and boron fiber in the form of fibers, flakes or particles [6][7][8][9]. Decrease in boron carbide percentages also decreases hardness [10]. Powder metallurgy procedures have points of interest over throwing strategy by disposing of isolation.…”

Powder metallurgy is one of the best methods to achieve uniform distribution of reinforcement in to the matrix. In this Paper, characterization of microstructure and hardness of aluminum alloy matrix composites reinforced with boron fiber particles prepared by powder metallurgy technique are investigated. The effects of boron fiber (Coarse particles size of 120 µm and Fine particles size of 50 µm) on mechanical properties were studied. Increasing the reinforcement of boron fiber content with 5%, 10% and15% into the matrix improved the mechanical properties. The percentage of boron fiber reinforcement increasing the strength of the hardness number is also increasing simultaneously, the aluminum alloys and boron fiber particles on the microstructure and mechanical properties of the composites were investigated. X-ray diffraction (XRD) and scanning electron microscopy (SEM) with Energy dispersive spectrum (EDS) analyses indicated. Analysis and observing microstructure of the composite is boron fiber particles are uniformly dispersed in the aluminum alloy matrix composites.
