Based on the observation results, the transformation mechanism of FFL microstructure was analyzed and proposed as that the fine γ/α lamellar colonies form at the high temperature in the α single phase region through the precipitating of the α plates on the four equivalent habit planes {111}γ, in each γ matrix grain and then evolve to the γ/α2 lamellar colonies of the FFL microstructure.
