Functionally Graded Materials (FGMs) are the emerging materials in which material properties vary continuously with position, in one direction. The present study is to fabricate a Functionally Graded Al/Si in situ material and to characterize it. Al /17wt.%Si alloy has been used to fabricate Al/Si FGM by centrifuge casting process specially designed for the purpose. The microstructural characteristic and hardness profile of these FGMs have been evaluated. The study shows the structure of this Al/Si alloy produced by this method changes from Hyper-Eutectic through to Hypoeutectic, with later having primary Al dendrites. It also reveals that hardness and the primary Si particles vary along the length of the sample
