The evolution of geometrically necessary dislocations (GND) in aluminum was studied using high-resolution EBSD. Small grains had higher GND density than coarse grains and were most pronounced at a strain of ∼9.8%, due to GNDs were more homogeneously organized at strain >9.8%. Furthermore, <111> oriented grains with higher Taylor factor stored more GNDs than <100> grains.
