摘　　要：应用电子背散射衍射(EBSD)技术研究退火工艺(单步法和两步法)对形变量为99%的镍基带中立方织构形成的影响。结果表明,随着退火温度的升高,镍基带中立方取向和其它取向的晶粒平均尺寸不断增加,立方取向晶粒的平均尺寸比其它取向晶粒的平均尺寸要大,而且随着退火温度的升高,这种晶粒尺寸优势不断的增加;低温退火时退火工艺对立方织构含量影响不明显,而高温退火时其立方织构含量大幅增加;相对于单步退火法,两步退火法能有效的提高镍基带中立方织构的含量。Influence of annealing processes（single step annealing and two step annealing） on microstructure and texture of deformed nickel substrate tapes were analyzed by electron backscattering diffraction（EBSD） techniques.The results show that the average grain size of both cube grains and other grains increases with increasing annealing temperature,the average grain size of cube grains is larger than that of other orientation grains.For single step annealing,the content of cube texture increases slowly at low temperatures,while at high temperatures the content increase significantly.Comparing with single step annealing,the percentage of cube texture in the nickel substrate tapes can be increased effectively by two step annealing.
