摘      要：Al/Mg bimetal was prepared by lost foam solid-liquid compound casting,and the effects of mechanical vibration on the filling and solidification behavior,microstructure and performance of the bimetal were *** show that the mechanical vibration has a remarkable influence on the filling and solidification *** is found that after mechanical vibration,the filling rate increases and the filling rate at different times is more uniform than that without *** addition,the mechanical vibration also increases the wettability between liquid AZ91D and A356 *** mechanical vibration reduces the horizontal and vertical temperature gradient of the casting and makes the temperature distribution of the whole casting more *** to the Al/Mg bimetal without vibration,the shear strength is improved by 39.76%after the mechanical vibration is applied,due to the decrease of the inclusions and Al_(12)Mg_(17) dendrites,and the refinement and uniform distribution of the Mg_(2)Si particles in the interface of the Al/Mg bimetal.
