Abstract

The present work is motivated by the tremendous interest in the functionally graded materials (FGMs). The properties of FGMs change gradually with the position. The property gradient in FGMs is caused by a position-dependent chemical composition, NS OF FGMs microstructure or atomic order. The overall properties of FMGs are unique and different from any of the individual material that forms it. One unique characteristic of FGMs is the ability to tailor a material for specific application. There is a wide range of applications of FGMs and it is expected to increase. In this paper we will make a brief survey of the most distinguished properties and some of the applications of FGMs.
