  • Aluminium dross AIMCs
    Kevorkijan, Varužan
    In this work, the potential of finely powdered aluminium dross by-product withan average particle size of 67 ▫$\mu$▫m as a cost effective reinforcement in discontinuously reinforced aluminium matrix ... composites (A356) was demonstrated. Using a standard rheocasting procedure, samples of composite material were obtained consisting of 20 vol. % of one as-received and three laboratory processed grades of dross particles which differed mainly in particle size and the level of impurities. Inspection of tensile properties of these different composite materials showed that a slight improvement in strength over the unreinforced matrix is achievable only by the introduction of fine dross particles with a particle size of less than 10 mm, while in composites with larger dross particles no strengthening effect was observed. In contrast, the evaluation of wear properties demonstrated that the introduction of coarse and even as-received dross particles in an aluminium matrix results in a significant improvement of wear resistance of the composite material.
