The orientation relationship and interfaces of Ni3Sn4 and Ni3Sn2 with the Ni (001) and (111) surfaces have been studied with transmission electron microscopy. Ni was evaporated onto the NaCl (001) and (111) surfaces to form epitaxial Ni thin films and Sn was evaporated onto the Ni film and heat treated to form Ni3Sn4 and Ni3Sn2. No orientation relationship between Ni3Sn4 and Ni was found. Two types of orientation relationships between £b-Ni3Sn2 and Ni were found: (1) (0002) £b-Ni3Sn2//(220)Ni and (01 0) £b-Ni3Sn2//(2 0)Ni on the (2 0) £b-Ni3Sn2/(001)Ni interface¡Fand (2) (0002) £b-Ni3Sn2 //(2 0)Ni and (01 0) £b-Ni3Sn2//(22 )Ni on the (2 0) £b-Ni3Sn2/(001)Ni interface.
