| Abstract: | The effect of mechanical vibration on the microstructure and property of a new high strength casting aluminum alloy was discussed.The results show that in the condition of using the vibration with different frequency and different time in the process of solidifying,the small crystalline grains can be achieved.While the vibration frequency is 30Hz continuing 60s,as a result of the fine grains,the microstructure of the alloy and the overall properties improve greatly.The new casting aluminum alloy with high s... |
