Notes:
Micro-orientation data of a high purity Al rolled up to total thickness reduction of 80% atroom temperature were determined using SEM-EBSD technique, conceptions of describingsubstructure information, such as subgrain misorientation (θcry), and average misorientation (θenv) ofcircumjacent subgrains for a special subgrain, etc., were suggested and corresponding GCDP-OI softpackage was developed. It is found that the subgrains sizes increase rapidly from about 2 to 7 μm withincreasing misorientations from 1° to 15°, and the total number frequency of which is more than 95%.However, taking into account local features of subgrais, whose sizes for Dcry/Denv 〉 1 are 2 timeslarger than that for Dcry/Denv 〈 1 on the same misorientation levels below 20°, and the relationshipsbetween misorientations and sizes are consistent with that if Dcry/Denv 〉 1, θcry/θenv 〉 1, vice versa
