EFFECT OF ANNEALING TEMPERATURE ON TEXTURE OF COLD-ROLLED Ni_(47)Ti_(44)Nb_9 SHEET

摘要

The textures of the cold-rolled and annealed Ni_(47)Ti_(44)Nb_9 sheets have been studied using the orientation distribution function (ODF) method. The results indicated that the cold-rolled sheet showed a dominant {100}_p face texture, and its recrystallization textures could be described with {001} <100>_p. Moreover, when the cold-rolled sheet was annealed at 700 or 850℃ , there occurred abnormal coarsening, thus forming a new kind of annealing texture {001} <110>_p.
