%X The properties of Fe_3Al-based intermetallic alloys at room temperature have been significantly improved through multi-alloying composition control and optimization of thermomechanical process. The elongation was increased from2--3% for as-cast state to 15 --20%, the yield strength up to 500 MPa. It is found that the elongated flattened grains, B_2 structure and dispersive second phase are beneficial to the comperehensive improvement of mechanical properties at room temperature.
