Metal matrix composite (N[MC) materials were manufactured using powder metallurgy (PM) techniques. Pure aluminum, Al, powder of mean particle size of 51 pm and alumina, AhO3, powder of 4 pm particle size were used as matrix and reinforcement, respectively. MNICs with four different weight fractions of reinforcement (e.g; Al-0wt.% AhO3, AI-2.5wt.% AhO3, Al-5wt.% AI2O3, and Al-1 0wt. %AhO3 ) were investigated The specimens were manufactured using hot compaction followed hot extrusion. Based on a preliminary study and on data published in the literature, two sets of processing parameters, designated as Scheme I and Scheme II, were used. The processing parameters …
