The Formation of Cube Texture in 50%Ni–50%Fe Alloy

The recrystallization process in a 50%Ni–50%Fe alloy sheet 96% cold rolled was studied by a transmission electron microscope. In the early stage of recrystallization, a cube grain grew mainly at the band-like structure consisting of (110) [1\bar12] and weak (100) [001] components of cold rolled texture. A high dislocation density region was found in a slightly grown cube grain when annealed at 490°∼520°C for 30 min. Such a region was found only one in each cube grain, and its size was compared to the subgrain size of the band-like structure. It was presumed that the cube grain grew from the region by subgrain boundary migration, without inverse Rowland transformation.
