Antiphase boundary (APB) orientation and energy in the superstructure L12

This paper is devoted to an electron microscope study of the antiphase boundaries (APB) in the ordered alloy Pd₃Fe, a theoretical explanation of the reasons for their preferred orientation, and a computation of the antiphase boundary energy with =1/2 110 {001} in alloys with the superstructure L1₂.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 3, pp. 59–61, March, 1979.
