摘要
通过背散射电子衍射技术检测并研究了铸轧-冷轧法制备超薄双零铝箔坯料过程中晶粒取向演变规律。结果表明,铸轧铝箔坯料中形成较强的(102)[221]、(101)[101]及旋转立方(001)[1-1-0]织构组分;随均匀化退火温度升高、保温时间延长,坯料的晶粒取向演变为立方织构,以(001)[100]和(101)[101]织构组分为主,且立方织构取向密度最大为15.786;中间退火后,立方织构(001)[100]取向密度降低至1.197。而热处理不能完全消除变形织构组分(101)[101],其存在于整个铝箔坯料制备过程。
Evolution of grain orientation in ultra-thin aluminum foil blank by casting-rolling and cold-rolling was analyzed by electron backscattered diffraction( EBSD). The results show that( 102) [221]texture,( 101) [101]texture and( 001) [1-1-0] rotating cube texture are formed in aluminum foil blank after cold-rolling. With the increasing of annealing temperature and holding time,the textures of the blank are mainly composed of( 001) [100] cubic texture and( 101) [101] texture. Cubic texture orientation density enhibits the maximum value of 15. 786,which is reduced to 1. 197 by the middle annealing,and( 101) [101]texture exists in the whole preparation process.
