研究了冷轧Ni 3Al多晶和单晶在退火过程中再结晶织构的发展。单晶中的再结晶织构，无论是无硼还是掺硼的，都包括单组分变形织构的所有8个35° 111 °旋转（接近黄铜取向）。在单晶中没有观察到退火孪晶，与多晶相反。多晶体的再结晶织构很弱，但可再现。它们的分量可以解释为±35° <$111 <$m旋转和变形基体的二阶孪生之间的折衷。
The recrystallization texture development during annealing of cold rolled Ni3Al polycrystals and single crystals was investigated. The recrystallization texture in single crystals, regardless whether boron-free or boron-doped, comprised all eight 35° 〈111〉 rotations of the single component deformation texture (close to the brass orientation). No annealing twins were observed in single crystals, in contrast to polycrystals. The recrystallization textures of polycrystals were very weak, but reproducible. Their components can be interpreted as a compromise between ±35° 〈111〉 rotations and second order twinning to the deformed matrix.
