The elongations of FeAl-Ti alloys were larger than that of the binary FeAl compound under an initial strain rate range of 2.08×10~(-4)-8.33×10~(-2) s~(-1), tested at 900-1000℃. The strain rate sensitivity index, m, is over 0.3 commonly. With the increase in Ti content in FeAl alloys, m value and elongation increase significantly. The maximum m value and the maximum elongation were up to 0.43 and 297% respectively. Microstructure analyses and TEM graphs show that grains became fine and subboundaries were formed during superplastic deformation, which resulted in the superplasticity in large grained FeAl-Ti alloys.
