摘要
The fracture behaviors of DO 3 ordered Fe 28Al alloys with or without V addition were studied. The results show that addition of element V into Fe Al alloy can improve the mechanical properties of the alloy. Contrasted with transgranular fracture of Fe 3Al alloy at room temperature, the Fe 3Al containing V has intergranular and transgranular cleavage mixed fracture mode. The theoretical calculation conforms that V addition could increase cleavage strength of Fe 3Al alloy from 98.405 7 kJ/mol to 173.144 5 kJ/mol in 〈111〉 direction and from 29.660 4 kJ/mol to 47.673 0 kJ/mol in 〈100〉 direction.
