摘　　要：采用电子背散射衍射(EBSD)等测试手段和分析方法,系统地研究了不同退火温度对冷轧纯钛板微观组织及织构的影响。结果表明:中间退火温度为700℃时,0.6 mm冷轧至0.25 mm后经700℃/1 h退火得到的再结晶组织更加均匀,残余应力更小,{0001}、{10-10}及{11-20}三个极图上的织构更加散漫,织构强度整体较弱,取向分布更加随机。A comparative and systematic study was conducted on the effects of annealing temperatures on the microstructure and texture of cold-rolled pure titanium plates using testing methods and analysis methods such as Electron Backscatter Diffraction(EBSD).The results show that when the intermediate annealing temperature is 700℃,the recrystallized structure of 0.25 mm plate obtained by cold rolling from 0.6 mm plate and 700℃/h treatment is more uniform with smaller residual stress.The textures on the{0001},{10-10}and{11-20}three pole figures are more scattered with weaker overall texture intensity,and the orientation distribution is more random.
