在Ni-9.3at.%的合金中，很难获得尖锐的立方织构钨基板用于涂层导体，由于其低堆垛层错能。通过引入中间回复退火工艺，对传统冷轧工艺进行了优化。在冷轧过程中，经过3次500°C × 2 h回复退火后，形变织构得到改善。经优化再结晶退火后，Ni-9.3at.%获得了立方织构含量为87.7%（<10°）的基板。中间退火对立方织构形成的影响归因于变形织构的改善和变形基体中预先存在的立方取向结构的增强。
It is difficult to obtain a sharp cube texture in the Ni-9.3at.% W substrate used for coated conductors due to its low stacking fault energy. In this paper, the traditional cold rolling procedure was optimized by introducing an intermediate recovery annealing. The deformation texture has been improved after three recovery annealing cycles at 500°C for 2 h during the cold rolling process. After optimized recrystallization annealing, a Ni-9.3at.% substrate with a cube texture content of 87.7% (<;10°) has been obtained. The effect of the intermediate annealing on cube texture formation is attributed to the improved deformation texture and to the enhanced pre-existing cube oriented structure in the deformed matrix.
