Small amount of cerium addition to Fe{sub 3}Al-based alloys results in enhancement of ductility and strength at ambient temperature. The improvements of tensile properties and creep resistance at high temperature of 600 C can also be achieved by combined addition of cerium with molybdenum, zirconium or niobium. Cerium addition changes the fracture ode of Fe{sub 3}Al-based alloys from transgranular cleavage or mixed transgranular cleavage and intergranular fracture to one of transgranular cleavage with portions of dimple fracture.
