Abstract

Functionally Graded Materials (FGM) have been continuously attracting attention in the recent days as they offer varied properties in an uniform manner which is otherwise not possible for common engineering materials. However, production of FG products is still a practicing art. Producing functionally graded materials in the form of layered structure consisting of Al-Mg-Cu (AMC) alloy and Rice Husk Ash (RHA) by Controlled mold filling procedure is presented. The density, impact strength, and hardness in each layer of the FG product were measured. The microstructures of these layers were studied. The results obtained show that functionally graded materials produced by the controlled mold filling process exhibited an improvement in impact strength and hardness and a reduced density with addition of the rice husk ash.

Keywords
