Molybdenum/stainless steel/titanium functionally graded materials (FGM), which will be used as long life cladding tubes in a fast breeder reactor, have been fabricated by slurry dipping and sintering process, emphasizing the increase in corrosion resistance to liquid sodium and fission products. Slurries of different compositions were prepared by mixing the appropriate amount of Mo, SUS304 and Ti powders in water with polyvinyl alcohol. Cylindrical substrates were formed by die pressing of stainless steel and alumina powders. The substrates were dipped in the slurry to coat the surface subsequently dried in air and debinded in Ar. They were encapsulated in Pyrex glass tubes and then HIPed 2h at 1050°C at a pressure of 200MPa. The microstructural observation in the cross section of the sintered compacts has revealed that the dipped layers were formed, in which no defects such as small cracks and residual pores were observed. Some intermetallic compounds were observed in the FGM layer as detected by EPMA.
