Abstract Optical microscopy, transmission electron microscopy and scanning electron microscopy were used to examine microstructure features of the directionally solidified Ni3Al alloy deformed under tension at high temperature. The results show that initial columnar grain boundaries have not obviously changed during the deformation under higher strain rate and there are no substructure within the columnar grains. When strain rate is lower, the initial columnar grain boundaries firstly change into sawtooth shape and then evolve into small grain belts with increasing strain during superplastic deformation. The average grain size in belt is about 15 mm containing both low angle grain boundaries and high angle grain boundaries. It is suggested thata continuous recovery and recrystallization process took place during superplastic deformation in DS Ni3Al alloy.

Key words: directional solidification Ni_3Al high temperature deformation microstructure
