| Abstract: | More investigations have been done by scholars on the performance and its relevant mechanism of rear-earth elements in aluminum and its alloys, but a little on the perfornlance to increase obdurability of high strength casting aluminum alloy. In this paper, the impact of rear- earth elements to the alloy ZL205A was studied. The results showed that rear - earth elements have significant action in the alloy both in fining crystalline particle of aluminum alloy and in significantly enhancing obdurability of the alloy. |
| Keywords: | rear-earth element alloy ZL205A structure impact |
