- Carbon nanotube-reinforced aluminum composite produced by induction melting Muhammad Mansoor Muhammad Shahid Ingeniería Metal Fractography Lattice strain Crystallite size Induction melting Aluminum/carbon nanotube composite is a promising candidate material for aerospace applications owing to its high strength-to-weight ratio. Because of the low density of carbon nanotubes (CNTs), their dispersion is difficult in molten metal. We investigated induction melting, a fairly distinct approach to facilitate the dispersion of CNTs in molten aluminum. The nanocomposites were characterized using scanning electron microscopy, X-ray diffraction, transmission electron microscopy and mechanical testing. Refinement in crystallite size ( ∼ 320 nm) and increase in lattice strain ( ∼ 3.24 × 10 − 3 ) were observed in the composites. A simultaneous increase in yield strength ( ∼ 77%), tensile strength ( ∼ 52%), ductility ( ∼ 44%) and hardness ( ∼ 45%) was observed. Induction melting appeared to be a potential method to fabricate aluminum–CNTs composites.
