Recent advancement in materials processing has resulted in the evolution of advance composite known as Functionally Graded Materials (FGMs). FGMs are multi-layered structures with composition and/or microstructure that vary spatially across the volume of the material. This chapter presents an overview of the concept of functionally graded materials in terms and its history. The present and potential applications of FGMs are briefly described, as well as various classification methods. Processing of FGM using laser metal deposition (LMD) is also discussed as well as the influence of LMD process parameters on the quality of laser processed materials. Studies that have been conducted on metal-metal FGM produced LMD are presented. Finally, a study on the microstructure and microhardness of laser deposited compositionally graded 316L/17-4PH was also presented.
