The Effect of Rare-earth on the Refining Property of the Al-Ti-B-RE Intermediate Alloy
The effect of rare-earth on the refining property of the Al-Ti-B-Re intermediate alloy was investigated. The results indicated that it was effective not only on the size and distribution and refining of the second particles in the alloy but also on the delay of fading property and remelting property of refiner. With the addition of rare-earth the Al-Ti-B-RE made obvious improvement on the refining property than that of the Al-Ti-B.
