Outline of Final Research Achievements

Selected formation of an ordered variant during disorder-order transformation in A1-L10 alloys has been found by ordering heat treatment under magnetic field. However, quantitative evaluation of nucleation ratio of ordered variants is complicated because of dynamical electron diffraction. In this study, Precession Electron Diffraction (PED) technique, which reduces effect of dynamical electron diffraction, has been applied in Fe-40at.%Pt alloy ordered under magnetic field and ratio of superlattice reflections have been evaluated quantitatively.
