摘要：

Additional spots are observed on diffraction patterns of the gamma-TiAl phase alloyed with iron for zone axes of the type <111> or <101>. These diffraction patterns are explained assuming a modification of the stacking sequence of {111}(L10) Variants of this modification are observed to form domains within the grains Of 7 phase.
