The composite materials formed by powder metallurgy are mostly used in industry due to their excellent properties such as low density, high strength, and hardness. The aim of this study is to produce functional graded Al material reinforced with macro-sized Al2O3. To fabricate the aluminum matrix composite, commercial Al 2124 aluminum alloy powder (from Gürel Makina), which is used in aerospace and defense industries, was chosen as a matrix material. Powder metallurgy was used to produce the functional graded material because it allows an easy incorporation of reinforcement phase into the matrix. The sintered samples were characterized using optical microscopy, SEM, and X-Ray diffraction analysis. The results show that functional graded material structure and the transition interlayers were achieved by the presented process.
