Based on the experiment of laminated pouring and accumulated liquid forging of 2A12 aluminum alloy, Interface mechanical properties of formed component with large ratio of altitude and diameter were investigated by means of SEM and Instron materials drawing equipment.The results show that it is feasible to apply the method of laminated pouring and accumulated liquid forging into forming components with large ratio of altitude and diameter.Pouring temperature, reheated temperature of die, pressure, pouring layers and standing time are important technological parameters that influences on the mechanic properties.When pouring temperature is 740℃, reheated temperature of die is 480℃, pressure is 500kN ( specific pressure is 218.4MPa), pouring layers is three layers and standing time is 5s, the mechanical properties of interface is very good, microstructure is equiax crystal.
