摘　　要：测定了锆－２．５Ｗｔ％铌合金在冷变形量为２０％，５０％及４００℃退火后的板织构，计算了织构系数，讨论了织构形成、发展与工艺的关系。结果表明，冷加工变形量越大，织构越强烈；冷加工变形织构在４００℃／２４ｈ退火后不仅不会消失，反而会得到加强，这是由于择优取向的亚晶在退火回复过程中变得更加完整的原因。he cold deformation and low temperature annealing textures in Zr-2.5wt%Nb sheet were measured,the realated texture coefficientes were computed.The realation of texture with procedure are discussed. The resultes show that the larger the cold deformation texture,the more intense the texture.That cold deformation texture become stronger at 400℃ annealing is believed to result from the perfection of preferred orientation subgrains during annealing recovery.
