摘　　要：采用显微硬度仪、金相显微镜和X射线衍射仪研究了退火温度对冷轧Nb+Ti-IF钢的硬度性能、金相组织和织构的影响。试验结果表明:随着退火温度的升高,退火试样的维氏硬度降低,晶粒由轧制的扁长状长成等轴或近似等轴状态,γ-纤维织构不断吞并α-纤维织构而增强,对应的α-纤维织构则不断减弱。从工业生产和节约能源的角度考虑,Nb+Ti-IF钢的再结晶退火温度应控制在800℃左右。The influence of annealing temperature on the hardness,microstructures and textures of the cold-rolling Nb＋Ti-IF steel were studied in this paper.The results show that the hardness decreases and the grains become equiaxed when the annealing temperature increases.The γ fibre texture becomes stronger while the α fibre texture becomes weaker with the annealing temperature increasing.The annealing temperature for the cold-rolling Nb＋Ti-IF steel should be controlled at about 800℃ for saving the energy and processing.
