摘要

The mechanical properties of Fe-36.5/100 Al (mole fraction) intermetallic alloy at elevated temperatures were measured. The results indicate that the specific elongation of the alloy increases significantly with the temperature increasing from 600 deg. C to 1000 deg. C and the maximum of specific elongation is up to 115/100 when the alloy is deformed at 1000 deg. C. The dislocation features in the alloy were also investigated by transmis- sion electron microscopy (TEM). There exist not only a large number of gliding dislocation lines but also a number of helical dislocations in FeAl alloy after deformed at elevated temperatures.
