• FeAl intermetallic alloy
• superplasticity
• activation energy

The activation energy of large-grained FeAl alloys during superplastic deformation has been investigated. The flow activation energy was measured to be about 370, 290 and 260 kJ.mol(-1) for Fe-36.5Al, Fe-36.5Al-1Ti and Fe-36.5Al-2Ti (mole fraction, %) alloys, respectively, which are much lower than the creep activation energy previously measured in FeAl alloys. Ti addition can decrease the grain size and the activation energy of FeAl alloy.
