| Abstract: | The mechanical properties of Fe\-3Al\|based alloys at room temperature and high temperature were studied after carburizing upon different time.It is discovered that carburation decreases the strength and ductility and increases the order\|transition temperature of the alloys.Carbon infiltrates into Fe\-3Al alloy by the form of solid solution and when carbon infiltration amount is over, its solid solubility,carbides will precipitate at the grain boundaries,thus decreases the strength and ductility of the alloy. |
