Relationship between Parameters of Solid Solution and Grain Boundary Ensemble in Pd₃Fe Ordered Alloy with L1₂ Superstructure

Abstract:

By X-ray diffraction and scanning electron microscopy using the method of back-scattered electrons the parameters of the solid solution (the lattice parameter and the mean-square displacement of atoms) and the grain boundary ensembles in the alloy Pd₃Fe with the superstructure L1₂ have been investigated depending on the degree of the long-range atomic order. The relationship between the proportion of the twins Σ3 in the spectrum of special boundaries and the mean-square displacement of atoms was detected.
