Abstract: The effect of V on mechanical property of Fe₃Al-based ordered alloy was studied. The results show that V can refine grains which improves strength and plasticity of Fe₃Al. As contrasted with transgranular fracture of Fe₃Al at room temperature, the Fe₃Al containing V has intergranular and transgranular cleavage mixed fracture mode which is gradually changed into void fracture as tensile temperature increases. The DO₃-ordered Fe₃Al with V has maximum tensile strength at 700 ℃ which is much higher about 200 ℃ than that of DO₃-ordered Fe₃Al without V.
