|Summary||The present document provides preliminary results of aluminium metal matrix composites reinforced with granulated slag and electric arc furnace dust. The composites were synthesized using powder metallurgy techniques. Green density of the compacts was determined as a function compacting pressure and reinforcing particles weight per cent. Sintering experiments suggest good densification in Al/granulated-slag composites and slight densification in Al/electric-arc-furnace dust composites. The hardness and compressive strength of the sintering compacts was determined in order to compare the mechanical properties of the composite material as a function of the granulated slag and electric arc furnace dust content. At present, the best results concern the Al/granulated-slag composites, reaching compressive strengths up to 370 MPa.
