Abstract: | The method of transmission electron microscopy is used to study the dislocation structure in single crystals of the Ni
3
Fe ordered alloy for different degrees of strain. The 1812], 011], 111] and 001] single crystal orientations are examined.
The superdislocation splitting (r) is measured for different degrees of strain, distributions of r are constructed, and their
average values 〈r〉 are estimated. The 〈r〉-ε curves are constructed. With the use of the experimental r values, the effective
energy of antiphase boundaries ζ* is estimated.
