Effect of Rare Earth Metals on the Mechanical Properties and ...
The present study was performed on A356 and A413 alloys in nonmodified and Srmodified conditions. To these alloys, pure rare earth RE metals, mainly lanthanum La and cerium Ce , were added in the amount of 1 wt each, individually or combined. The results showed that the addition of 2 RE leads to a significant reduction in the grain size 60 compared to the base alloy. However, it ...
