The Fracture of Transgranular Cleavage of Fe3Al and the Intergranular Fracture of FeAl

The most principal obstacle to the development of intermetallic compounds Fe3Al and FeAl as constructional materials is always the room temeprature （RT） embrittleo-ment. The early studies indicated that the poor RT ductility of polycrystalline Fe3Al with DO3 structure was due to the weakness of grai...

Summary:The most principal obstacle to the development of intermetallic compounds Fe3Al and FeAl as constructional materials is always the room temeprature （RT） embrittleo-ment. The early studies indicated that the poor RT ductility of polycrystalline Fe3Al with DO3 structure was due to the weakness of grain boundaries, which results in the easy intergranular fracture. It was found from the experiments in recent years
