Abstract:Materials that are functionally graded and have a layered structure made of nickel and aluminum were fabricated by powder metallurgy procedure. Al/Ni FGM consist of five layers. The functionally graded material sample starts with pure aluminum and ends with pure nickel. the graded layers were (25 Ni-75Al) %, (50 Ni-50 Al) % and (75 Ni-25Al) %. Samples were sintered at a temperature 600° C. Apparent density, green density, porosity, and shrinkage of each layer were measured.
