Factors Determining the Orientation Relationships between Iron Deposits and (111) FCC Substrates

J. Echigoya*, M. Nemoto* and H. Suto*

Iron was vacuum deposited onto (111)fcc substrates of nickel, copper and silver. The orientation relationships between the deposit and the substrates have been examined by transmission electron microscopy and selected area diffraction. The iron/substrate interfaces take the orientation relationships of {110}Fe//{111}fcc. In the iron-silver system, the orientation relationship is [001]Fe//[110]Ag, that is the Nishiyama-Wassermann relationship. In the case of iron-copper system, the iron deposits rotate about an axis normal to the substrate and lead to the orientation relationship in the range from Nishiyama-Wassermann's to Kurjumov-Sachs's. For the iron on nickel, the K-S relationship is more pronounced compared to the case of iron on copper system. These results can be understood by the concept of good atomic fitting area at the interface.
