| Abstract: | Al4.5Cu4Ce alloy was prepared by slope vibration casting technique. Effects of pouring temperature, cooling method and vibration voltage on alloy solidified structure were studied. Experiments show that these parameters of the alloy have a significant impact on crystal nucleation and crystal growth. The microstructure of the water cooling copper mold casted Al4.5Cu4Ce alloy at 700 ℃ with slope vibration is fine,and nearly spherical non-dendritic structure with the average grain diameter of 38.3 μm, the average grain roundness of 2.31. |
