Abstract The dislocation features in FeAl alloy after superplastic deformation have been investigated by TEM. The results show that the initial large grains are divided into small grains through the formation of sub-grain boundaries during the superplastic deformation,and the sub-grain boundaries can develop into small grain boundaries by absorbing the dislocations in sub-grains. Meanwhile, the new grains can be further divided by newly formed sub-grain boundaries. After repeating the above process of evolution, the initial large grains are fined and the superplastic deformation keeps going on.
