Abstract

Functionally graded material with aluminum matrix have many applications in the aerospace and automotive industry due to high strength and good wear resistance, as they can obtain optimum condition by centrifugal casting method. A390 HYPEREUTECTIC ALLOY was cylindrically cast into a cylindrical steel mould as the base alloy with rotational speed of 1200, 1400, 1600 and 2000 rpm by vertical centrifugal casting method. Microstructure of samples, VOLUME FRACTION OF REINFORCEMENT PARTICLES and their hardness from inner wall to outer wall were investigated by optical microscope (OM). Results show that because of smaller density of primary Si particles than molten Al, these particles move to the inner wall of the samples due to centrifugal force and create a gradient distribution from inner layer to middle region. Moreover, the casting sample with rotational speed of 1400 rpm was chosen as the optimum sample. Possible consequences of characteristics of this sample are discussed.
