It is observed that the mean grain size decreases with extended ball-milling time. The grain refinement rate falls from an initial 9.7 nm/h at the ball-milling time of 2 h to 2.8 nm/h at the ball-milling time of 16 h. Conversely, the lattice strain initially rises and then slightly declines when the ball-milling time exceeds 8 h.
