Synthesis and characterization of Al-B4C nano composites

Publication date: Available online 15 July 2019Source: Materials Today: ProceedingsAuthor(s): Deepak M. Shinde, Suswagata Poria, Prasanta SahooAbstractIn the present study, effect of incorporation of varying weight percentages (0.5, 1, 1.5, and 2) of boron carbide nanoparticles in aluminum-silicon alloy LM6 is investigated. Nanocomposites are fabricated using ultrasonic vibration assisted stir casting process. Field emission scanning electron microscopy (FESEM) and Energy Dispersive spectroscopy images are used to characterize the base alloy and fabricated composites. Nanoparticles are seen to be homogeneously incorporated in the alloy matrix. Refinement in the microstructure is seen effecting improvement in the hardness and density of composites. Hardness values of as cast composites are obtained using Vickers microhardness tester which are found to be higher than the base alloy.
