摘要:
The laws of the crystal orientation in the annealing process of Ni5W long tapes by the reel-to-reel method and Ni5W short tapes by the static method in laboratory are obviously different. Results show that with higher heating rate of dynamic annealing process, the formation of Cube nuclei is insufficient and the growth of Cube nuclei is slow. Meanwhile, Cube orientation fraction stops growing and S orientation fraction does not decrease at some point, and Cube orientation fraction increases rapidly with further increase of temperature. With the insulation heat treatment, Cube orientation nucleation and growth advantage are shown in static annealing process. In the nucleation stage, many Cube nuclei are obtained, and Cube nuclei grow rapidly with the increase of temperature. The relationship between the reel-to-reel method and the static method were studied for guiding the recrystallization annealing of long tapes which helps the transformation of the study of the short tapes to the industrialization of the long tapes.
