The goal of the present research is to introduce the Tungsten (W) nanoparticles as reinforcement into Al 6063 alloy to produceAl?W nanocomposites by the FSP technique. The vol% of the reinforcement was varied from 3 to 12 with a step of 3,besides the unreinforced Al matrix was considered as 0 vol% for comparison. The role of W nanoparticles in the Al 6063matrix has been exhaustively investigated using advanced characterization techniques such as XRD analysis to observe thephases, FESEM to detect the distribution of reinforcements with their interparticle spacing and the average grain sizes, TEManalysis to study the strengthening factors, new phase formation at the interface between AA 6063 matrix and W particles,the morphology of the W nanoparticles. The achieved average matrix grains size was 42, 2, and 0.9 μm for 0, 6, and 12vol% W nanocomposites, respectively. The obtained results disclosed the uniform dispersion of W nanoparticles, withoutany agglomeration, and with the absence of intermetallic compounds. The hardness and wear resistance of the fabricatednanocomposites were increased incommensurate with the incorporation of heavy metallic W element as reinforcementparticle; which was due to the proper dispersion of W nanoparticles, refinement of matrix grains to ultrafine level, generationof dislocations, and clear interface between Al 6063 matrix and W nanoparticles. In a nutshell, AA 6063?12 vol% Wnanocomposite has achieved the higher hardness (120 HV), lower wear rate (0.13 mm3/m), and friction coefficient (0.33)than other nanocomposites.
